OmniORB2 has been tested with egcs-1.1.1 + binutils-2.9.1.0.14 on x86 linux 2.0 and glibc 2.0.x systems. This release of egcs fixes quite a few bugs in the previous version, and it is strongly recommended that you get hold of this version. Please see the mailing list for news of success with egcs on other platforms, or if you manage to use egcs successfully on a new platform yourself, then please let us know. Some older news:OmniORB2 has been tested with egcs-1.1b + binutils-2.9.1.0.14 on x86 linux 2.0 and glibc 2.0.x systems (e.g. Redhat 5.1). Remember that egcs-1.1b must be compiled with --enable-threads. Egcs-1.0 was released in Dec 1997 and was followed by egcs-1.0.1 in Jan 1998. The stock compiler can compile this distribution cleanly. However, the code it generates does not have thread-safe exception handling. This would result in random crashes when omniORB programs are run. Teemu Torma has provided a patch to egcs-1.0 to make it generates thread-safe exception handling code. OmniORB2 has been tested with the patched compiler and successfully run on the following platforms:
However, there is a compiler bug in egcs-1.0 that make it unable to compile some of the sequence templates in omniORB2. The bug might be fixed in the latest snapshot of egcs but I'm not certain. Teemu Torma's patch is reported to be working on Solaris, HPUX and AIX as well. Andrey Slepuhin has run the omniORB2_testsuite with egcs on AIX. Let me know if you have success in running the testsuite on other platforms. The latest development snapshot of egcs seems to have incorporated the patch but I have not tested it myself. I've left my binaries for x86 Redhat linux 5.0 and alpha Redhat linux 5.0 in: ftp.uk.research.att.com:/pub/linux/egcs-1.0.alphabin.tgz (4M) and ftp.uk.research.att.com:/pub/linux/egcs-1.0.x86bin.tgz (4M) The diff against the unpatched egcs-1.0 is in: ftp.uk.research.att.com:/pub/linux/egcs-1.0-thread-safe-eh.diff (60K) The diff is based on Teemu Torma's patch + patch for RedHat 5.0 by H.J. Lu + my bug fix to get the thread-safe-eh stuff to work with linux-threads (or any draft 10 or later posix thread implementations). For x86 Redhat linux 5.0, you must update binutils to 2.8.1.0.17. If you are building the compiler yourself, you have to apply this patch to the resulting spec file:
23c23
> %{pg:-lgmon} %{pg:-lc_p} %{!pg:-lc} %{pthread:-lpthread}
---
> %{pg:-lgmon} %{pg:-lc_p} %{!pg:-lc} %{pthread:-rpath /usr/local/lib/pthread -lpthread}
This is to ensure that the thread-safe-eh version of the stdc++ library is picked up when the executable is run. |
