Hi, I'm trying to build GCC 4 for the LynxOS. The native compiler didn't work so I'm trying for the crosscompiling route. I build the binutils 2.15 as: ../binutils-2.15/configure --prefix=/usr/local --target=i386-lynx-lynxos --disable-nls and I have built GCC 4.0.1 with this patch reverted to enable coff target as default for lynxos: http://gcc.gnu.org/ml/gcc-patches/2004-07/msg00501.html with this flags: $ ../gcc-4.0.1/configure --prefix=/usr/local --target=i386-lynx-lynxos --disable-nls --with-gnu-as --with-gnu-ld --with-headers the headers and libs of the system are under /usr/local/i386-lynx-lynxos The binutils were build fine, and the gcc stops on building libstdc++-v3 (so, I tought that the c compiler was build fine and ran make install to see what happens). Then, If I run: gcc -V 4.0.1 -b i386-lynx-lynxos hello.c -o hello The system says about unresolved symbols: /cygdrive/c/DOCUME~1/rcabral/LOCALS~1/Temp/ccrW7xqg.o(.text+0x7):hello.c: multiple definition of `_main' /usr/local/lib/gcc/i386-lynx-lynxos/4.0.1/../../../../i386-lynx-lynxos/lib/init1.o(.text+0x0):.file: first defined here /cygdrive/c/DOCUME~1/rcabral/LOCALS~1/Temp/ccrW7xqg.o(.text+0x31):hello.c: undefined reference to `_puts' /usr/local/lib/gcc/i386-lynx-lynxos/4.0.1/../../../../i386-lynx-lynxos/lib/libc. a(runmainthread.s)(.text+0x29):runmainthread.s: undefined reference to `main' collect2: ld returned 1 exit status So, I checked with nm about the symbols on the libc of the LynxOS and they exists in there but without the "_" appended. So, I generate an object file (".o"). And then I changed the symbols of the object file with objcopy to the same name but without the "_" like this: i386-lynx-lynxos-objcopy --redefine-sym _main=main --redefine-sym _puts=puts hello.o hello2.o After that, I ran: gcc -V 4.0.1 -b i386-lynx-lynxos hello2.o -o hello And it links without errors. Then I copy the executable file to the LynxOS machine and it did work fine (It printed "hello"). So, after all this, my question is: What should I do to tell to GCC to not append "_" on the symbols? Did I build GCC or binutils the wrong way? I'm using cygwin as the host. Any help is appreciated, Thanks in advance, (and sorry for my bad English) -- ----------------------------------------------- Roberto Cabral Correo: roberto.cabral( at )gmail.com
