Can't build windows gem about bool HOT 6 CLOSED

@aslakhellesoy are you forcing CC, CXX, LDFLAGS or CPPFLAGS in your environment? That affects compilation.

I'll check later today against my office computer and let you know.

from bool.

@luislavena - no none of these environment variables are defined. Thanks for looking into this Luis!

from bool.

@aslakhellesoy the problem is here:

https://github.com/cucumber/bool/blob/master/ruby/ext/bool_ext/extconf.rb#L7-L9

You're invoking the compilation of a C library by shelling out. That has nothing to do with rake-compiler.

libbool itself is unaware of cross-compilation. You will need to change bool Makefile to be able to use CC and AR from the environment.

Then, you will be able to do:

Dir.chdir(LIBBOOL) do
  ENV["CC"] = RbConfig::CONFIG["CC"]
  ENV["AR"] = RbConfig::CONFIG["AR"]
  ENV["LDSHARED"] = RbConfig::CONFIG["LDSHARED"]
  system "make clean all"
end

Now, a few things I see:

• You are compiling libtool.o with -shared which will produce a shared object, yet you're saving it as object file (.o) That definitely is not what you want
• At the same time you're generating a static library libbool.a, but that will not use the shared object you're creating.

Perhaps I'm getting the makefile incorrectly, but I see those as problems.

If you want to build a shared object (.so) use what RbConfig::CONFIG have which is usually right for the platform. Replace your hardcoded command by $(LDSHARED) and you can add to your Makefile

LDSHARED?=$(CC) -shared

Also found that -lfl produces problems for me on OSX:

$ make CC=gcc
flex lexer.l
bison parser.y
gcc  -I/opt/local/include  -c -o parser.o parser.c
gcc  -I/opt/local/include  -c -o lexer.o lexer.c
gcc  -I/opt/local/include  -c -o bool_ast.o bool_ast.c
gcc -shared -o libbool.o lexer.o parser.o bool_ast.o -lfl
ld: library not found for -lfl
collect2: error: ld returned 1 exit status
make: *** [libbool.o] Error 1

But even beyond that I'm having problems with a simple rake compile natively on my OSX box.

Here is the diff so far of what I've made:

https://gist.github.com/4684251

But I'm stuck here:

ar rcs libbool.a lexer.o parser.o bool_ast.o
checking for bool_ast.h... yes
checking for parse_bool_ast() in -lbool... no
libbool is missing.

and from mkmf.log:

Which indicates having issues with libbool.a

How you run this locally?

As you can see my box uses clang and not gcc. Maybe that's why.

from bool.

Yeah, I use GCC 4.7, and I think doesn't come with fl library.

Ruby and other libraries were compiled with it, so cannot change to clang.

Either way, I think the changes I sent helped, right? Will bool be >= 1.9.3?

Sorry for top posting. Sent from mobile.
