Re: [Sdcc-user] Reference on how to make lib and header for PIC16F887

If you have the SDCC sources at your disposal, try
$ cd /path/to/sdcc/support/scripts
$ mkdir build
$ cd build
$ ../inc2h.pl 16f886 /path/to/gputils
$ ../inc2h.pl 16f887 /path/to/gputils

# If /path/to/gputils/headers/p16f877.inc exists, you should obtain two
# files: pic16f877.c and pic16f877.h. These only need to be copied into
# the right places in device/lib/pic/libdev and device/lib/include/pic
# respectively:

$ cp pic1*.c /path/to/sdcc/device/lib/pic/libdev
$ cp pic1*.h /path/to/sdcc/device/include/pic
$ cd /path/to/sdcc/device/lib
$ make model-pic14
$ make install

pic16f877 is completely built, the 16f886 and 16f887 series are not yet
supported by gputils without patches and thus broke our daily builds.
You find the header files in device/include/pic, the device libraries
reside in device/lib/pic/libdev/disabled_pic16f88[67].c. Just rename
them to pic16f88[67] respectively and rebuild the library. Sorry for the
inconvenience, gputils are to blame ;-)

Using the provided files should be easier---and safer.

HTH,
