* System libcrypto.dylib and libssl.dylib are used by system ld on MacOS X.
|
|
|
|
|
|
NOTE: The problem described here only applies when OpenSSL isn't built
|
|
with shared library support (i.e. without the "shared" configuration
|
|
option). If you build with shared library support, you will have no
|
|
problems as long as you set up DYLD_LIBRARY_PATH properly at all times.
|
|
|
|
|
|
This is really a misfeature in ld, which seems to look for .dylib libraries
|
|
along the whole library path before it bothers looking for .a libraries. This
|
|
means that -L switches won't matter unless OpenSSL is built with shared
|
|
library support.
|
|
|
|
The workaround may be to change the following lines in apps/Makefile and
|
|
test/Makefile:
|
|
|
|
LIBCRYPTO=-L.. -lcrypto
|
|
LIBSSL=-L.. -lssl
|
|
|
|
to:
|
|
|
|
LIBCRYPTO=../libcrypto.a
|
|
LIBSSL=../libssl.a
|
|
|
|
It's possible that something similar is needed for shared library support
|
|
as well. That hasn't been well tested yet.
|
|
|
|
|
|
Another solution that many seem to recommend is to move the libraries
|
|
/usr/lib/libcrypto.0.9.dylib, /usr/lib/libssl.0.9.dylib to a different
|
|
directory, build and install OpenSSL and anything that depends on your
|
|
build, then move libcrypto.0.9.dylib and libssl.0.9.dylib back to their
|
|
original places. Note that the version numbers on those two libraries
|
|
may differ on your machine.
|
|
|
|
|
|
As long as Apple doesn't fix the problem with ld, this problem building
|
|
OpenSSL will remain as is. Well, the problem was addressed in 0.9.8f by
|
|
passing -Wl,-search_paths_first, but it's unknown if the flag was
|
|
supported from the initial MacOS X release.
|
|

|
* Parallell make leads to errors
|
|
|
|
While running tests, running a parallell make is a bad idea. Many test
|
|
scripts use the same name for output and input files, which means different
|
|
will interfere with each other and lead to test failure.
|
|
|
|
The solution is simple for now: don't run parallell make when testing.
|
|
|
|
|
|
* Bugs in gcc triggered
|
|
|
|
- According to a problem report, there are bugs in gcc 3.0 that are
|
|
triggered by some of the code in OpenSSL, more specifically in
|
|
PEM_get_EVP_CIPHER_INFO(). The triggering code is the following:
|
|
|
|
header+=11;
|
|
if (*header != '4') return(0); header++;
|
|
if (*header != ',') return(0); header++;
|
|
|
|
What happens is that gcc might optimize a little too agressively, and
|
|
you end up with an extra incrementation when *header != '4'.
|
|
|
|
We recommend that you upgrade gcc to as high a 3.x version as you can.
|
|
|
|
- According to multiple problem reports, some of our message digest
|
|
implementations trigger bug[s] in code optimizer in gcc 3.3 for sparc64
|
|
and gcc 2.96 for ppc. Former fails to complete RIPEMD160 test, while
|
|
latter - SHA one.
|
|
|
|
The recomendation is to upgrade your compiler. This naturally applies to
|
|
other similar cases.
|
|
|
|
- There is a subtle Solaris x86-specific gcc run-time environment bug, which
|
|
"falls between" OpenSSL [0.9.8 and later], Solaris ld and GCC. The bug
|
|
manifests itself as Segmentation Fault upon early application start-up.
|
|
The problem can be worked around by patching the environment according to
|
|
http://www.openssl.org/~appro/values.c.

* solaris64-sparcv9-cc SHA-1 performance with WorkShop 6 compiler.
|
|
|
|
As subject suggests SHA-1 might perform poorly (4 times slower)
|
|
if compiled with WorkShop 6 compiler and -xarch=v9. The cause for
|
|
this seems to be the fact that compiler emits multiplication to
|
|
perform shift operations:-( To work the problem around configure
|
|
with './Configure solaris64-sparcv9-cc -DMD32_REG_T=int'.
|
|
|
|
* Problems with hp-parisc2-cc target when used with "no-asm" flag
|
|
|
|
When using the hp-parisc2-cc target, wrong bignum code is generated.
|
|
This is due to the SIXTY_FOUR_BIT build being compiled with the +O3
|
|
aggressive optimization.
|
|
The problem manifests itself by the BN_kronecker test hanging in an
|
|
endless loop. Reason: the BN_kronecker test calls BN_generate_prime()
|
|
which itself hangs. The reason could be tracked down to the bn_mul_comba8()
|
|
function in bn_asm.c. At some occasions the higher 32bit value of r[7]
|
|
is off by 1 (meaning: calculated=shouldbe+1). Further analysis failed,
|
|
as no debugger support possible at +O3 and additional fprintf()'s
|
|
introduced fixed the bug, therefore it is most likely a bug in the
|
|
optimizer.
|
|
The bug was found in the BN_kronecker test but may also lead to
|
|
failures in other parts of the code.
|
|
(See Ticket #426.)
|
|
|
|
Workaround: modify the target to +O2 when building with no-asm.

|
|
|
* Problems building shared libraries on SCO OpenServer Release 5.0.6
|
|
with gcc 2.95.3
|
|
|
|
The symptoms appear when running the test suite, more specifically
|
|
test/ectest, with the following result:
|
|
|
|
OSSL_LIBPATH="`cd ..; pwd`"; LD_LIBRARY_PATH="$OSSL_LIBPATH:$LD_LIBRARY_PATH"; DYLD_LIBRARY_PATH="$OSSL_LIBPATH:$DYLD_LIBRARY_PATH"; SHLIB_PATH="$OSSL_LIBPATH:$SHLIB_PATH"; LIBPATH="$OSSL_LIBPATH:$LIBPATH"; if [ "debug-sco5-gcc" = "Cygwin" ]; then PATH="${LIBPATH}:$PATH"; fi; export LD_LIBRARY_PATH DYLD_LIBRARY_PATH SHLIB_PATH LIBPATH PATH; ./ectest
|
|
ectest.c:186: ABORT
|
|
|
|
The cause of the problem seems to be that isxdigit(), called from
|
|
BN_hex2bn(), returns 0 on a perfectly legitimate hex digit. Further
|
|
investigation shows that any of the isxxx() macros return 0 on any
|
|
input. A direct look in the information array that the isxxx() use,
|
|
called __ctype, shows that it contains all zeroes...
|
|
|
|
Taking a look at the newly created libcrypto.so with nm, one can see
|
|
that the variable __ctype is defined in libcrypto's .bss (which
|
|
explains why it is filled with zeroes):
|
|
|
|
$ nm -Pg libcrypto.so | grep __ctype
|
|
__ctype B 0011659c
|
|
__ctype2 U
|
|
|
|
Curiously, __ctype2 is undefined, in spite of being declared in
|
|
/usr/include/ctype.h in exactly the same way as __ctype.
|
|
|
|
Any information helping to solve this issue would be deeply
|
|
appreciated.
|
|
|
|
NOTE: building non-shared doesn't come with this problem.

* ULTRIX build fails with shell errors, such as "bad substitution"
|
|
and "test: argument expected"
|
|
|
|
The problem is caused by ULTRIX /bin/sh supporting only original
|
|
Bourne shell syntax/semantics, and the trouble is that the vast
|
|
majority is so accustomed to more modern syntax, that very few
|
|
people [if any] would recognize the ancient syntax even as valid.
|
|
This inevitably results in non-trivial scripts breaking on ULTRIX,
|
|
and OpenSSL isn't an exclusion. Fortunately there is workaround,
|
|
hire /bin/ksh to do the job /bin/sh fails to do.
|
|
|
|
1. Trick make(1) to use /bin/ksh by setting up following environ-
|
|
ment variables *prior* you execute ./Configure and make:
|
|
|
|
PROG_ENV=POSIX
|
|
MAKESHELL=/bin/ksh
|
|
export PROG_ENV MAKESHELL
|
|
|
|
or if your shell is csh-compatible:
|
|
|
|
setenv PROG_ENV POSIX
|
|
setenv MAKESHELL /bin/ksh
|
|
|
|
2. Trick /bin/sh to use alternative expression evaluator. Create
|
|
following 'test' script for example in /tmp:
|
|
|
|
#!/bin/ksh
|
|
${0##*/} "$@"
|
|
|
|
Then 'chmod a+x /tmp/test; ln /tmp/test /tmp/[' and *prepend*
|
|
your $PATH with chosen location, e.g. PATH=/tmp:$PATH. Alter-
|
|
natively just replace system /bin/test and /bin/[ with the
|
|
above script.

|
* hpux64-ia64-cc fails blowfish test.
|
|
|
|
Compiler bug, presumably at particular patch level. It should be noted
|
|
that same compiler generates correct 32-bit code, a.k.a. hpux-ia64-cc
|
|
target. Drop optimization level to +O2 when compiling 64-bit bf_skey.o.
|
|
|
|
* no-engines generates errors.
|
|
|
|
Unfortunately, the 'no-engines' configuration option currently doesn't
|
|
work properly. Use 'no-hw' and you'll will at least get no hardware
|
|
support. We'll see how we fix that on OpenSSL versions past 0.9.8.
|
|
|
|
* 'make test' fails in BN_sqr [commonly with "error 139" denoting SIGSEGV]
|
|
if elder GNU binutils were deployed to link shared libcrypto.so.
|
|
|
|
As subject suggests the failure is caused by a bug in elder binutils,
|
|
either as or ld, and was observed on FreeBSD and Linux. There are two
|
|
options. First is naturally to upgrade binutils, the second one - to
|
|
reconfigure with additional no-sse2 [or 386] option passed to ./config.
|
|
|
|
* If configured with ./config no-dso, toolkit still gets linked with -ldl,
|
|
which most notably poses a problem when linking with dietlibc.
|
|
|
|
We don't have framework to associate -ldl with no-dso, therefore the only
|
|
way is to edit Makefile right after ./config no-dso and remove -ldl from
|
|
EX_LIBS line.
