[fpc-pascal] mips cross compiler libraries (and crti.o) problem

[Luca Olivetti]

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:

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
