Syntax error in configure script when building?

[digitaltrousers]

Hi. Sorry if I've done something dumb, but ./configure fails for me. I believe I've installed all the prerequisites, and I've run aclocal libtoolize autoconf automake --add-missing ./configure ...and configure fails with the following: root@kali:/usr/local/share/smbusb# ./configure checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes checking whether make supports nested variables... yes checking for gcc... gcc checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... no checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ISO C89... none needed checking whether gcc understands -c and -o together... yes checking for style of include used by make...

Thanks for any help.

Hi, Do you have the pkg-config package installed? I'll add it to the requirements if it's that. I think it was a default on my distro but it might not be on yours.

[digitaltrousers]

It wasn't installed, but installing it doesn't seem to have changed anything.

[karosium]

Did you re-run all the commands on a clean source tree afterwards? Installing pkg-config should've dropped the pkg.m4 file containing the PKG_PROG_PKG_CONFIG macro into the appropriate directory for aclocal to find it and merge it into the aclocal.m4 file it builds when you run it. If you can't find the macro in that file when you do a text search for it's name then it's file is either missing or aclocal is looking in the wrong place. This may be helpful in that case.

Right you are! I also had to manually copy firmware.h from the firmware directory to the lib directory to get it to build. I also had the error loading the shared libraries, which you answered in issue#1. Thanks heaps.

[karosium]

Hrmm.. it never should've gotten to a point where the manual firmware copy was necessary.. unless the sdcc checks passed but sdcc still couldn't build the firmware for some reason.. did you do 'git submodule update' to pull fx2lib into the tree after cloning? ( one of the things that git should probably either do automatically or at least display a message about IMO.. ) Either way, glad you got it to work.

[digitaltrousers]

I didn't know about 'git submodule update'. Thanks for the tip.
