[SOLVED] Different outcome running makepkg vs running the commands.

Question

Hi all,
I'm trying to build fatback, for blackarch mainly but I'll upload to AUR too, and I'm having some weird outcomes.
If I run makepkg -sfic on this, it fails with a load of compiler errors, but if I run the configure & make separately, it works fine, only complaining about flex library missing. See here
What gives?
Makepkg log
Command output 1
Command output 2
Command output 3
EDIT: Solution was a mix of environment variables for me, and the original dev making some mistakes, see last post.

Thanks for the text version.
I think we missed some makepkg flags.  I just tried this PKGBUILD - I get the same error you do with makepkg.  When I build manually I also get the flex errors that you just posted *unless* I export the makepkg variables - then I get the same error as with makepkg.  But above I missed "CPPFLAGS" - so try the following in the (clean) source directory:
source /etc/makepkg.conf
export CFLAGS
export LDFLAGS
export CPPFLAGS
export CXXFLAGS
./configure
make
This produces the same error as the makepkg for me.
EDIT: and I found the problem.  The upstream source was trying to pass definitions of data types through compiler "DEF" flags (eg -Dsize_t=unsigned)  This conflicted with the internal typdefs for these types included from header files.  Removing these absurd definitions allows it to compile.  Stand by for a patch/sed command for the PKGBUILD.
EDIT: Insert this in the PKGBUILD after the configure command and before make in the build function:
sed -i 's/-Doff_t=long -Dpid_t=int -Dsize_t=unsigned//' Makefile
For explanation: the DEF flag defined "size_t" as "unsigned" so anytime the former was encountered in the code, it was replaced with the latter.  But in the code, included header files had lines like "typedef size_t unsigned;" which the preprocessor then turned into "typdedef unsigned unsigned;" which doesn't make any sense to the compiler.
