Dear Michel,

there is a GSL library, but our build system seems to enforce a particular folder structure that seems not compatible with the one in the Cygwin gsl-devel package.

Best,

Johannes

Hi Johannes,

these packages were made a long time ago by Sebastien. Maybe, they should be updated.

from the cygwin web site, I have the impression that there is a GSL Cygwin x86-64 package for GSL.

I don't know if one can use a Cygwin package in Mex file or whether one must have a mingw64 compiled one

Dear all,

is there a particular reason, GSL is only contained in the 32 bit file http://www.dynare.org/build/dynare-mingw32-libs.zip but not in http://www.dynare.org/build/dynare-mingw64-libs.zip ? I couldn't find any information on a restriction to 32 bit.

Best,

Johannes

The C-files of https://www.cygwin.com/ml/cygwin-announce/2013-08/msg00044.html like gsl_cdf.h seem to be in

usr\include\gsl

but the expected folder structure as in Sébastien's 32 bit package is one that distinguishes folders

bin include lib share

Can you explain in details please? What is the path in gsl-devel and what is the path expected by our build system?

Thanks Sébastien. when do you think that we will have to consider recompiling these libraries for MINGW64 in order to cross-compile Dynare for Windows?

For MEX files we need MinGW-compiled DLLs. We never supported Cygwin-compiled MEX files.

I don't know why the 64-bit GSL is not in the ZIP. Most probably it is an error. I may have forgotten to include it in the ZIP file, but the binary is probably in /usr/local/mingw64 (or something like that) on karaba.

Thanks

Michel

The only reason for recompiling them is to keep up with new upstream releases. It's not necessary to be super reactive, but you need to check from time to time, at least because of bugfixes and security issues. I was more or less updating the libraries every 3 months, to match the Dynare release cycle (but it's better not to recompile them just before a release, in order to avoid breaking something in the last minute).

I think that there are some per-library specific compilation instructions in the org file that I gave to Stéphane before leaving.
