Set your linker to output a 32-bit executable.

tried:
Quote: gcc -m32 fasm.o -o fasm |

You need to install the 32-bit libraries. Check with your OS documentation for how to do that. It's probably something like glibc-devel.i386

I've been trying. I am using Xubuntu 14.04. ia32-libs used to do it, I think, but it was phased out. libc6-i386 has been installed, also multilib support for gcc and g++ (I have 5.3).
lnterestingly, Code: gcc -m32 -L/usr/lib32/ fasm.o -o fasm /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/5/libgcc.a when searching for -lgcc /usr/bin/ld: cannot find -lgcc /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/5/libgcc_s.so when searching for -lgcc_s /usr/bin/ld: cannot find -lgcc_s collect2: error: ld returned 1 exit status Still searches the 64-bit libs, in spite of -L/usr/lib32/ It must be something really dumb... |

Perhaps using LD directly (without going through GCC) will help?

Another failed attempt:
Code: ld -m elf_i386 fasm.o /usr/lib32/libgcc_s.so.1 -o fasm ld: fasm.o: undefined reference to symbol 'exit@@GLIBC_2.0' //lib/i386-linux-gnu/libc.so.6: error adding symbols: DSO missing from command line . Do you know what libraries I should link against - it appears I have to manually list them (similar discussion found elsewhere here in Unix messages. |

Code: ld -m elf_i386 fasm.o /usr/lib32/libgcc_s.so.1 /usr/lib32/crtn.o /usr/lib32/crt1.o /usr/lib32/crti.o /usr/lib32/libc.so -L/usr/lib32 -o fasm This actually links, but the executable is wacky: Code: ./fasm bash: ./fasm: No such file or directory even though the file is there...

Have you marked it as executable? I'm not sure if LD does this automatically or not.

It's executable:

Any ideas? |

I've used the same system with older versions of fasm a year ago. The new distribution of fasm does not seem to have an executable (to my surprise) and the instructions suggest just linking the fasm.o with gcc.
I vaguely remember going through a similar exercise a few years back. I should've kept notes.. Not that it would've helped - the 32-bit compatibility libraries have been changed. I've used fasm for many years without issues. On the other hand, my system is not at all remarkable - a 64-bit ubuntu with up-to-date gcc. I can't believe others haven't come acrosss this. Perhaps someone could statically link fasm on Ubuntu and post a binary... As a command-line tool, it does not use strange libraries, and should run on at least debian systems. I am at a bit of a loss (will investigate deeper today). Just when I started feeling good about the state of linux and fasm (deleting expletives and disparaging thoughts...) Thanks for your help. |

Looks like I goofed somehow. Thanks.
