Hello,

I am lost :/ I installed FPC 3.2.2 from the TAR file as described here: https://www.freepascal.org/docs-html/user/usersu5.html

I did "sudo ./install" and kept everything default.

Now, I want to build fpc main from Git. I do:

make clean all OPT='-O- -gw -godwarfsets -gl -Xg' DEBUG=1 INSTALL_PREFIX=$mypath FPMAKEOPT="-T $usethreads"
make install OPT='-O- -gw -godwarfsets -gl -Xg' DEBUG=1 INSTALL_PREFIX=$mypath FPMAKEOPT="-T $usethreads"

It takes a while and then I get this error:

make[1]: Entering directory '/home/pi/software/fpc/src' make -C packages smart
make[2]: Entering directory '/home/pi/software/fpc/src/packages' ./fpmake compile -T  --localunitdir=.. --os=linux --cpu=arm -o -gl -o -Ur -o -Xs -o -O2 -o -n -o -Fl/usr/lib/gcc/arm-linux-gnueabihf/8 -o -O- -o -gw -o -godwarfsets -o -gl -o -Xg -o -CVglobal-dynamic -o -darm -o -dDEBUG -o -dRELEASE
--compiler=/home/pi/software/fpc/src/compiler/ppcarm -bu -o -XX -o -CX The installer encountered the following error:

make[2]: *** [Makefile:1965: smart] Error 1

OK, I searched for the error and found this page:
https://wiki.freepascal.org/FPMake#Could_not_find_unit_directory_for_dependency_package_.22rtl.22

It says: "In general the fpmake system scans the places typically used for fpc installations."

OK, I kept everything by default but it still doesn't find FPC directory... So OK, I want to set it, but what directory is it? I thought that the install script gives me the directory, but I don't find it there. When I run the install script again, I get:

Running on linux

Writing sample configuration file to /etc/fppkg.cfg Saved old "fppkg.cfg" to "fppkg.bak"
Writing sample configuration file to /etc/fppkg/default Saved old "default" to "default.bak"

End of installation.

Do you know what I am missing to build FPC main from Git? Btw. I can build pas2js with a simple "make" just fine... I am lost :(

Thanks

Even if I do
export FPCDIR=/usr/lib/fpc/3.2.2
before make (where the installer installed FPC), I get the same error: Could not find unit directory for dependency package "rtl" required for package "a52"

I have no idea, does anybody know what I am missing? I would appreciate any help.

Ondrej

P.S.: My whole script looks like:

# directory where FPC should be built into
mypath="~/software/fpc/exp"

# install directory of FPC 3.2.2
export FPCDIR=/usr/lib/fpc/3.2.2

# number of threads
set usethreads=4

cd src
# now I am in the fpc src directory from Git main
make clean all OPT='-O- -gw -godwarfsets -gl -Xg' DEBUG=1 INSTALL_PREFIX=$mypath FPMAKEOPT="-T $usethreads"
make install OPT='-O- -gw -godwarfsets -gl -Xg' DEBUG=1 INSTALL_PREFIX=$mypath FPMAKEOPT="-T $usethreads"
cd ..

OK, I made the fpmake command work:

I added "--globalunitdir=.." to the fpmake line:

./fpmake compile -T  --localunitdir=.. --os=linux --cpu=arm -o -gl -o -Ur -o -Xs -o -O2 -o -n -o -Fl/usr/lib/gcc/arm-linux-gnueabihf/8 -o -O- -o -gw -o -godwarfsets -o -gl -o -Xg -o -CVglobal-dynamic -o -darm -o -dDEBUG -o -dRELEASE
--compiler=/home/pi/software/fpc/src/compiler/ppcarm -bu -o -XX -o -CX --globalunitdir=..

Now, the packages compile.

But the question still persists: why do you need it and what file do I have edit so that "make" works?

Btw. setting
  export FPCDIR=/home/pi/software/fpc/src
in my make script doesn't help (the ".." directs to /home/pi/software/fpc/src).

So I now know how to fix the fpmake command, but where do I have to fix it so that the make process works?

I found it...

I copied&pasted it from windows, on Linux it must be:

# number of threads
usethreads=4

Thanks anyway
