i have an error when i install gsl (with netbeans) - ruby

I try to install gsl gem for Ruby but it doesn't work. i have a matrix_complex.o error.
So is there a solution to install gsl for netbeans ?
or is there a fonction quantile in an other library?
Any help would be appreciated.

Getting some clues from https://github.com/romanbsd/rb-gsl/issues/2 I did the following on Ubuntu:
Uninstalled my existing gsl:
sudo apt-get remove gsl-bin libgsl0-dev libgsl0ldbl
Built a new gsl
wget ftp.gnu.org/gnu/gsl/gsl-1.14.tar.gz
tar xf gsl-1.14.tar.gz
cd gsl-1.14
./configure
make
sudo make install
Installed the gem
gem install gsl
This worked for me.


The above answer works as you can simply use version ~1.14 of both the GSL and ruby bindings (rb-gsl).
However, if you have installed GSL via homebrew (brew install gsl) or prefer version 1.15 you can alternatively specify the following repo in your Gemfile for the ruby bindings:
https://github.com/whistlerbrk/rb-gsl/
which is based off of:
https://github.com/30robots/rb-gsl/
This has the patch for gsl_matrix and the first repo also has a patch for newer versions of rubygems.

Compiling dhex under MINGW64?

I've downloaded dhex_0.69.tar.gz from http://www.dettus.net/dhex/ and unpacked it. The Readme says simply to run make.
When I try to build it in MSYS2 shell on Windows 10, compilation and linking proceed without any problems, I get an .exe, which works fine:
user#PC MSYS /d/src/dhex_0.69

However, this .exe will then depend on msys-ncursesw6.dll and msys-2.0.dll when ran outside of the MSYS shell (so, when ran in Command Prompt cmd.exe, which does raise an error - or in Power Shell, which does not raise an error; the program simply exits there).
So, I wanted to try and build it in MINGW64. Compilation completes, but with warning - and linking fails due to undefined reference to '_impure_ptr':

make: *** [Makefile:27: dhex] Error 1
Would anyone know what I need to do, in order to have dhex compiled under MINGW64 (so it does not depend on MSYS dlls anymore)?

I downloaded the package in question and figured out how to compile it with the MinGW-w64 64-bit toolchain provided by MSYS2.
First of all, install the relevant development tools and libraries:
pacman -S base-devel mingw-w64-x86_64-{ncurses,toolchain}
Next, you need to edit the Makefile that comes with the package. The LDFLAGS, CPPFLAGS, and CFLAGS values must be modified to the following:
LDFLAGS=
CPPFLAGS= -I$(MINGW_PREFIX)/include/ncurses
CFLAGS= -D__USE_MINGW_ANSI_STDIO=1 -O3 -Wall
Some explanation: It is very bad that the Makefile has hardcoded paths in LDFLAGS and CPPFLAGS, because if you were to use those paths then you would be using files from another toolchain (the msys-2.0.dll-based one). So we need to get to get rid of those. Also, to get rid of all the warnings about printf formatting, we must supply the -D__USE_MINGW_ANSI_STDIO argument.
Then, just run make.

Does anyone have a suggestion what I am missing or how I can install ruby-gsl and make it work?

This guy had a similar issue: Problems installing gsl gem
It would seem, from the top answer, that gsl 1.15 is not compatible with ruby-gsl, and that reverting to version 1.14 is necessary? You mention that you use gsl 1.15 in your post, so perhaps that is your issue?
