Help me anybody, please. My program runs on arm-linux system and
when it receive SIGTERM i can't handle this signal, program

May be it bug? Or where i can see rtl code which handle linux
signals. Exact same program normally handle SIGTERM signal on
i386-linux system.
Which FPC version, which ARM-linux system (eabi, oabi), how was your
compiler/rtl compiled?
fpc 2.4.0 eabi linux
FPC 2.4.0 had broken return trampolines for signals on EABI. This was
fixed in 2.4.2, but that version still contains a serious bug in the
handling of syscalls with 5 parameters or more that causes random errors.
making crosscompiler
make all OS_TARGET=linux CPU_TARGET=arm
BINUTILSPREFIX=/home/sem/gcc/arm-none-linux-gnueabi/bin/ NOGDB=1

You have to move -dFPC_ARMEL from CROSSOPT to OPT. The above command
will compile an OABI cross-compiler.

Thanks Jonas. I've corrected 'make' string, add -dFPC_ARMEL то OPT.
Recompile application with fpc 2.4.2 and now it works, signal handling
works fine. Thanks.
