Unable to extract GMP version information from gmp_version :mingw

Unable to extract GMP version information from gmp_version :mingw

[Jim McNamara]

HI all-
I am experimenting with mingW64 with cygwin.
My ./configure looks like this:
$ echo $LD_LIBRARY_PATHC:/cygwin/lib
$ ./configure --prefix=/home/user/cobol-3.1-rc1 --host=x86_64-w64-mingw32
checking for gmp... nochecking for libgmp... nochecking gmp.h usability... yeschecking gmp.h presence... yeschecking for gmp.h... yeschecking for gmp.h... (cached) yeschecking if linking against libgmp with "-lgmp" works... yeschecking matching GMP version... configure: error: Unable to extract GMP version information from gmp_version
I installed the gmp package for mingw64. I went in and installed libgmp mingW64 package and the headers for in devel section of the cygwin installer.
I have the file libgmp.dll.a in c:/cygwin/lib
Please let me know if there is anything i can do to get past this error.
thanks,roboloki

Please figure out how to copy and paste including line terminators, or paste
into an editor and reformat before pasting into email.

You should normally be building in a directory e.g build, separate from that in
which configure resides e.g.

	$ mkdir build
	$ cd build
	$ ../src/configure ...

in which you should find config.log which should show all the details of all the
programs generated and run to check all the features required and all the
results from those runs.

I have found it useful if not necessary to install libgmp-devel with
mingw64-{x86_64,i686}-gmp, pkg-config with mingw64-{x86_64,i686}-pkg-config, and
similarly with other packages required for cross-builds.

Have you ever used a cross-compilation toolchain before?

Not sure what you are trying to achieve there, but even if it was
working it would be wrong.

Is your configure script set up to actually work with cross-compilation?
Your output doesn't seem to contain any notion of the configury checking
the cross toolchain.

Correct.

Whatever devel package you found there is most likely for Cygwin, but
it's hard to know without the package name.  The mingw64-* packages are
all standalone devel packages, only the Cygwin packages are split into
runtime and devel.

That's not the link library for MingW, but for Cygwin.

Maybe you look at some of the cross-compiled stuff in Cygwin and take it
from there?

Thanks Achim.

I fixed the ld_library_path.

I was wondering about the tip you gave me on devel packages not being split
from runtime in mingw. Now I know for sure.

I since added the bin directory to path for the mingw files for the x64
directory.

Very cool.  I have to crash now. I will work on this later today.

Have a good night.

Fwd: Unable to extract GMP version information from gmp_version :mingw

[Jim McNamara]

Hi Brian and Achim,

I built gnucobol with cygwin and mingw.  I may not need cross compiling. I
read that the permissions are easier to deal with in mingw so I got out the
mingw tools.

I thought that I'd try out deploying a program under mingw with cygwin
outside cygwin without the permission issues i ran into with posix/windows.

Thanks,
Roboloki
