I am just trying my first app using lazarus for a windows background.
I am getting some linker errors trying to build a library, but I do
not understand what the problem is.
Here are the follwing errors:
Code: [Select]
/usr/bin/ld: /opt/fpc/lib/fpc/2.0.4/units/x86_64-linux/rtl/system.o:
relocation R_X86_64_32S against `TC_SYSTEM_ISMULTITHREAD' can not be
used when making a shared object; recompile with -fPIC
/opt/fpc/lib/fpc/2.0.4/units/x86_64-linux/rtl/system.o: could not read
symbols: Bad value
callconv.lpr(26,1) Error: Error while linking

Can you help?

Hi,
I am getting a similar problem when compiling my library.
It works well in 32-bit mode but I get the following error when
linking in 64-bit mode.

Linking libfpacore2.so
/usr/bin/ld: /usr/lib64/gcc/x86_64-suse-linux/4.1.2/crtbegin.o:
relocation R_X86_64_32 against `_Jv_RegisterClasses' can not be used
when making a shared object; recompile with -fPIC
/usr/lib64/gcc/x86_64-suse-linux/4.1.2/crtbegin.o: could not read
symbols: Bad value
fpacore2.lpr(39,3) Error: Error while linking


I am using openSUSE Linux 10.2 x86_64

Thank you,
Shaun

PS: How do I recompile with -fPIC from Lazarus?

Hi,

I have found out that this is a Free Pascal problem. I do not know the
solution yet, but have not given up yet.

The -fPIC compile option is a red herring, it is listed because the
loader (ld) assumes that the code was compiled with gcc.

There was a suggestion to use the -Cp command line switch with the
free pascal compiler, but I have had no success.

Cheers
Shaun
