Hi,
I would like to be able to make scientific 2D plots (Y against X)
within an Ada code itself. I've been taken a look at PLplot but the
installation is cumbersome for a Windows machine. The installation of
PLplot for Windows is at:
http://www.miscdebris.net/plplot_wiki/index.php?title=Specifics_for_various_platforms#Windows
.. The installation is as follows:

cd plplot
mkdir buildmingw
cd buildmingw
cmake -G "MinGW Makefiles" -DCMAKE_INSTALL_PREFIX=install ..
mingw32-make
mingw32-make install

I decided to go for the MinGW instillation by downloading the exe file
from http://sourceforge.net/projects/mingw/files/ . I also got cmake
for Windows here: http://www.cmake.org/cmake/resources/software.html .

Now, on running the fourth instruction for installing PLplot (see
above), I get:

C:\plplot-5.9.6\buildmingw>cmake -G "MinGW Makefiles" -
DCMAKE_INSTALL_PREFIX=ins
tall ..
CMake Error at C:/Program Files/CMake 2.8/share/cmake-2.8/Modules/
CMakeDetermine
CCompiler.cmake:44 (MESSAGE):

CMake Error: Error required internal CMake variable not set, cmake may

Missing variable is:
CMAKE_C_COMPILER_ENV_VAR
CMake Error: Error required internal CMake variable not set, cmake may

les/CMakeCCompiler.cmake
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

C:\plplot-5.9.6\buildmingw>

I chose in the installation options to let cmake create the necessary
system paths. I wonder why the environment variables
CMAKE_C_COMPILER_ENV_VAR and CMAKE_C_COMPILER were not created during
the installation. I have the GNAT compiler. and for C I have the
Borland C++ Personal and MVS 2008 and 2010 compilers. Any suggestions?

Thanks a lot...

Your question isn't really Ada-related, but about PLplot installation.
Please post your question to the PLplot general discussion list. The
sign-up page is

https://lists.sourceforge.net/lists/listinfo/plplot-general

And yes, PLplot installation is cumbersome. It's available on a lot of
different machines which is partly why it's hard to install on any
one, requiring cmake to be installed first.

Thanks for the link. I've now indeed post the question on PLplot
discussion list. I posted this question here as I hoped someone had
gone through the same experience with PLplot as I did.

Best wishes
YC
