Compile fails on Ubnutu 10.10 X86_64

[Tabasco]

These commands are basically a pkg-config equivalent for perl. If you just type these commands by themselves in a terminal, you should get the appropriate compiler and linker options for embedding perl in that environment.

perl -MExtUtils::Embed -e ccopts
perl -MExtUtils::Embed -e ldopts

So what PERL_FLAGS=$(shell perl -MExtUtils::Embed -e ccopts) is actually doing is setting the PERL_FLAGS variable to the output of the command 'perl -MExtUtils::Embed -e ccopts'.

On my system (10.04 x64) the output of those commands is as follows:

-D_REENTRANT -D_GNU_SOURCE -DDEBIAN -fno-strict-aliasing -pipe -fstack-protector -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/lib/perl/5.10/CORE

And

-Wl,-E -fstack-protector -L/usr/local/lib -L/usr/lib/perl/5.10/CORE -lperl -ldl -lm -lpthread -lc -lcrypt

Additionally, the perl vars should be getting passed to the final COPTS and LINKOPTS vars.

COPTS=$(WFLAGS) ... $(DFLAGS) $(MYSQL_FLAGS) $(PERL_FLAGS)
LINKOPTS=$(COPTS) ... $(MYSQL_LIB) $(PERL_LIB)

I'm in 10.04 x64 but I wouldn't think that the environment would be so drastically different in 10.10.

While I understood what you mean and I have tried that, but it starts screaming at me with

/bin/sh: -D_REENTRANT: not found

on every line.

On a second look it looks like I had to manually add the perl libs to the variable lines and fix the fact they were not executed in shell first (like you stated and I was close to resolving). Check the output of diff from std makefile.a64 (makefile.bak for me) and the one I used (makefile)

$ diff makefile makefile.bak

I took a look at makefile.a64 and it's quite a bit different from the one I'm using, but I had been compiling a 32 bit binary due some past issues.

Notably, the line

gcc -MM $(COPTS) `$(PERL_FLAGS)` $$i | sed "s#^[^ ]*:#$$f:#g"; \

would need the `$(PERL_FLAGS)` section removed as we've already executed the commands above and the appropriate flags should now be appended to COPTS and LINKOPTS.

SVN indicates that the targeted makefiles have not been updated for a few years so it may be wise to start with the main makefile and adjust for architecture.
