Hello,
I built an fpc-3.0.4 mips cross compiler on kubuntu 18.04 using the
prepackaged mips binutils with
make all BINUTILSPREFIX=mips-linux-gnu- CPU_TARGET=mips OS_TARGET=linux
sudo make crossinstall BINUTILSPREFIX=mips-linux-gnu- CPU_TARGET=mips
OS_TARGET=linux
When I try to compile the program I get this error:
luca@seis:~/Datos/lgmounter$ ppcrossmips lgmounter.pas

lgmounter.pas(274) Error: Error while linking
lgmounter.pas(274) Fatal: There were 1 errors compiling module, stopping
Fatal: Compilation aborted
I copied libc.so and libdl.so from the target into the directory
/home/luca/mipslibs
I also had to copy crtbegin.o crtend.o crti.o crtn.o from an openwrt
buildroot for the target (is that correct? I couldn't find them on the
target)
What I tried:
1) putting this in /etc/fpc.cfg
#ifdef cpumips
-Fl/home/luca/mipslibs
#endif
2) adding a file in /etc/ld.so.conf.d with /home/luca/mipslibs and
running ldconfig
3) putting in the PATH a custom mips-gnu-linux-ld that adds an
--rpath=/home/luca/mipslibs/ before calling ld [*]
but the error message is always the same.
What am I doing wrong?
Bye
