Hi,
I would like to report a problem about compiling a simple code with gcc (g++)
from: /opt/gcc295/bin/gcc
Im using the old gcc compiler.
stefan@jupiter:~> gcc --version
2.95.3
stefan@jupiter:~> which gcc
/opt/gcc295/bin/gcc
Lyx-1.3.2 can't compile using gcc-2.95.3 due some problems I think with
libstd++ . Have a look:
#include
#include
#ifdef F77_DUMMY_MAIN
# ifdef __cplusplus
extern "C"
# endif
int F77_DUMMY_MAIN() { return 1; }
#endif
int
main ()
{
QString s("mangle_failure");
#if (QT_VERSION < 221)
break_me_(\\);
#endif
;
return 0;
}
This code works fine with gcc-3.3.1
When I set my PATH to /opt/gcc295/bin the compiler will give:
stefan@jupiter:~> export PATH=/opt/gcc295/bin:$PATH
stefan@jupiter:~> g++ -O -Wno-non-template-friend -ftemplate-depth-30
-I/usr/lib/qt3/include -L/usr/lib/qt3/lib -isystem /usr/X11R6/include test.cc

collect2: ld returned 1 exit status
any idea what can we do. Lyx132 can't compile because ./configure fails
exactly to this point.
Many thanks
Stefan
