If you work with windows, you should install cygwin (http://www.cygwin.com) 
which gives you a bash shell where you have an unix-like environment. In this 
environment you can easily configure, make etc.

Or just RTFM, it's all explained.

I am using mingw to compile it under Windows. You can find it here:
http://www.mingw.org/
However to compile sdcc you also need bison and flex, you can find
them in gnuwin32 package at: http://gnuwin32.sourceforge.net/
Also if your target is PIC microcontroller, then you also need
gputils. Get it from: http://gputils.sourceforge.net/

Good luck :D

btw: there is a script in support/scripts directory called somethig like
sdcc_cygwin_mingw32 . ( you can modify it to exclude support for non-pic
processors )

It should get you running, when everything is compiled ( before make install
) go to lib directory and compile the libs for your pic.
In any case you'll need cygwin environment to compile sdcc on windows, mingw
is just a way to compile/link it, to work without cygwin.

Hello,

I probably do not have MinSYS properly installed. The log is attached.

Is it possible to just run following:
sdcc $SOME_SDCC_PARAMS pic18f2455.c
gpasm $SOME_GPASM_PARAMS pic18f2455.asm
gplib $SOME_GPLIB_PARAMS pic18f2455.o

to have just the desired LIB file ? Or it is just not possible ?

Thank you,
Vaclav

Probably yes, the Makefile causes
	
../../../../bin/sdcc --asm=gpasm -mpic16 -p18f452 \
	--std-c99 -I. -I../../../include/pic16 \
	-Wa,-q --fommit-frame-pointer --obanksel=9 \
	--denable-peeps --optimize-goto --optimize-cmp \
	--optimize-df --i-code-in-asm \
	-o "../build/libdev/pic18f2455.o" \
	-c "pic18f2455.c";
rm -f "../build/libdev/pic18f2455.lib";
gplib  -c "../build/libdev/pic18f2455.lib" ../build/libdev/pic18f2455.o

to create pic18f2455.lib from pic18f2455.c. Maybe this is what you want,
after having adjusted some path names?!? In your case, I would also
replace -p18f452 with the actual device used, i.e. -p18f2455. I will
look into the Makefile to see why this is not done in the default libs
and change it (if it's not too difficult ;-))...

Raphael

Hello, thank you for your answers. But please before you should have read the question. I did have not asked about compilation of the whole package. That's not what I wanted to do. I asked how to compile single library.

Anyway Raphael just answered me - thank you very much.
