How can I compile a 32-Bit ELF with 64-Bit Linux?

[Fred556]

Hello,

I have OpenSuse11.1 and would like compile a 32Bit Elf File.

But I have no project. Only one dpr file and this compile. So no config exists.
Is there a compiler command to inlcude this in dpr file?

Hello,

when I compile my project with command
fpc test.pas

And I check them with
"file test" Then it told me
test: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), for GNU/Linux 2.4.0,statically linked, stripped

How can I compile a 32-bit LSB executable in a OpenSuse 11.1 64-Bit.

find a x86 version of fpc.
Then build a "new" fpc with it so rtl and fcl is compiled for x86.

Code: [Select]

fpc_source_dir> make all PP=your_path_to_ppc386install it and make sure you fpc.cfg contains something like (in my case)

Code: [Select]

# 32-bits
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/*
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/rtl
# 64-bits
-Fu/usr/lib64/fpc/$fpcversion/units/$fpctarget
-Fu/usr/lib64/fpc/$fpcversion/units/$fpctarget/*
-Fu/usr/lib64/fpc/$fpcversion/units/$fpctarget/rtl

Now you have a 32bit fpc installation. Next is lazarus.
Compile the LCL for 32 bit:

Code: [Select]

lazarus_source_dir> make lcl PP=ppc386
Now you can compile for 32bit or 64bit
