I am working on it right now. After many days of frustration, I have finally
managed to get gcc2.7.2 and a *static* version of libg++-2.7.1 working.
Here's what I did:
1. Compiled and installed new assembler (v2.6) from binutils-2.6
2. Compiled and installed gcc2.7.2 (used new assembler during compilation)
3. Compiled and installed static libg++-2.7.1 using gcc2.7.2, and the new
assembler
I have tried to compile and install a *shared* version of libg++, but
encountered the following problems:
1. compiler driver kept passing '-k' to the assembler to indicate PIC code;
-k was no longer a valid option for the new assembler
Fix:
edit the compiler specs file, and remove -k option passing to the
assembler;
you can find out the name of the specs file by invoking gcc -v on some
sample code;
2. after the first problem was fixed, linker dumped core when it was trying
to create a shared library. I have tried using new linker, but that
required me to recompile and relink crt0.o, gcrt0,o, etc. and most of the
existing libraries. I have tried re-compiling and re-linking libm.so, but
new assembler kept generating something on certain files, causing the
linker to dump core.
Anyway, I am currently trying a fix suggested by Tim Wilkinson. The fix
includes placing "#define SUPPORTS_WEAK 0" in gcc-2.7.2/config/i386/freebsd.h
I'll let you know if I am able to successfully build shared libg++-2.7.1
Rosty.
