Can reproduce this.
Would be helpful to know whether it works with older binutils, e.g. 2.15.92.0.2-r10. (Might want to quickpkg current one first).
(In reply to comment #2) > Would be helpful to know whether it works with older binutils, e.g. > 2.15.92.0.2-r10. (Might want to quickpkg current one first). It does not help. The same error after downgrading to binutils-2.15.92.0.2-r10.
When's the last time this worked for you?
* sci-chemistry/mopac7-1.10 Emerged at: Tue Dec 6 01:01:02 2005 Build time: 4 minutes, and 34 seconds
(In reply to comment #4) > When's the last time this worked for you? On this system it is my first attempt to install mopac7 as only recently a working blas-atlas has become available. I was able however, to emerge mopac7 on other system that uses stable x86 toolchain. This means that in order to reproduce this bug you should probably have an up to date ~x86 branch.
Any suggestions from toolchain people on why '-Wl,-defsym -Wl,MAIN__=main' no longer works with ~arch toolchain? It worked on my system as of a month ago.
what is the source code doing ? does it define the symbol "main" or "MAIN__" ? this works just fine for me: $ cat test.c int MAIN__(){return 0;} $ gcc test.c -Wl,--defsym,main=MAIN__
src/mopac7app.c:/* Main program */ int MAIN__(void)
so how is this a bug in binutils ? you define the symbol MAIN__ in your code but then try to use the linker scripts to generate a new symbol named MAIN__ and assign it to main ... thus ld rightly errors out when it cannot locate the symbol 'main' you attempted to assign MAIN__ to ... defsym MAIN__=main -> create symbol MAIN__ and assign symbol main to it defsym main=MAIN__ -> create symbol main and assign symbol MAIN__ to it

If I tried switching the order around, it breaks. If I removed it entirely, it doesn't produce the binary. But I just tried removing it now and things work as expected. Apparently some sort of toolchain bug was actually fixed and that broke my workaround. I'll take you guys off CC and just add a check for new toolchain.
Created attachment 77019 [details] mopac7-1.10.ebuild Please test this ebuild.
if you can provide an example of where the workaround was needed, that'd be nice for us to look into
(In reply to comment #12) > Created an attachment (id=77019) [edit] mopac7-1.10.ebuild > Please test this ebuild. Compilation was successful and produced working executable. Thanks.
This fix is not in the tree yet.
(In reply to comment #13) > if you can provide an example of where the workaround was needed, that'd be > nice for us to look into It was needed for a successful run of the configure script, then LDFLAGS had to be removed from Makefile* after configure was run. At least as current as December 6, I needed this. At the time, I had sys-devel/gcc-3.4.4-r1, sys-devel/binutils-2.16.1, sys-libs/glibc-2.3.5-r3. I now have sys-devel/gcc-3.4.5, sys-devel/binutils-2.16.1-r1, sys-libs/glibc-2.3.6-r2.
can you reproduce it still ? i just edited the 1.10, removed all the LDFLAG stuff, and then emerged with gcc-3.4.4/binutils-2.16.1 and gcc-3.4.5/binutils-2.16.1
Can't reproduce anymore.
