I am having problems getting FFTW 3.3 to work on my system.I downloaded the files from the fftw.org website, and then followed the installation instructions which told me to go to the terminal and type
./Configure
make
and everything seemed OK, but when I try and use FFTW in my C code by using the include<fft3> statement I get the fatal error
fatal error: 'fftw3.h' file not found
Does anyone know what I am doing wrong?
My IDE: Eclipse, My System: OSX 10.8
./configure
make
make install
You forgot the install command.

I am running MacOS Mojave Version 10.14.1. I am attempting to install the avr embedded development environment.
The command 'brew tap osx-cross/avr' works correctly however when the command 'brew install avr-libc' is used the following error is produced error
This produces a problem as files in c cannot be compiled due to avr-gcc being unavailable.
Any help and advice would be appreciated.
as #nos said, you need to run brew install avr-gcc.
More info here: https://github.com/osx-cross/homebrew-avr#installing-homebrew-avr-formulae
This worked for me: brew tap osx-cross/avr && brew install avr-gcc
Needed to expand brew's options of available software, as well as reference the updated avr-gcc instead of avr-libc.
I have the MinGW install previously working fine with MSYS. They are installed properly and functioning just well.
I installed the PortAudio library and did the install and got the success message after:
./configure
make
make install
When I try to compile samples:
c:\c>gcc patest_mono.c -o pa.exe
patest_mono.c:50:23: fatal error: portaudio.h: No such file or directory
#include "portaudio.h"
^
compilation terminated.
I'm new. I have a feeling I might be doing something fundamentally wrong with the way I'm trying to create the exe from compiling. It's been somewhat of a puzzle quest so far, but I've tried to figure it out and think I am close but completely missing something.
PATH variable ?
In the PortAudio MinGW build instructions I noticed
"The above should create a working version though you might want to
provide '–prefix=<path-to-install-dir>' to configure. "
I've tried adding C:\MingW\PortAudio into the user path. Doesn't work.
I've also tried running the commands in Bash and they come back with an error message "No Rule to make target 'paexpink'" either with the make command, and with gcc .c -o .exe I just get the same error message as compiling straight from the cmd prompt.
I found another source on stack overflow thread with no answers, but the user had commented that http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyaudio provided them a solution but I tried installing the 5 cpython binaries and under the assumption I did it right, it didn't work either.
Thanks for your help,
Julian
To build and install portaudio, you need to add -prefix=/c/<"path to base of the MinGW directory"> to the ./configure line.
For example: ./configure -prefix=/c/MinGW/
then continue the installation by doing
make
After that, do the
make install
and that should install the portaudio files into MinGW.
After it has finished installing, you need to add -lportaudio to the compile command whenever you compile any programs that you want to use PortAudio in.
For example: gcc -o test test.c -lportaudio
I just figured out how to do this today, so I may have accidentally forgotten a few steps.
I am trying to compile a mex file using openMp on win7_64. The file compiles fine, but when I try to run it I get the error:
Error: Invalid MEX file, the specified module could not be found
DependecyWalker tells me, that LIBGOMP_64-1.DLL is missing which I guess is the openmp library.
I installed the latest version of TDM-GCC and selected to install openmp support in the installer.
Is there anything else I have to install?
Thanks a lot
I copied the LIBGOMP_64-1.DLL from the mingw/bin directory to the directory where the mex file is and now it works...
I am using Mac OS X 10.8 with Xcode. I have installed the jansson library, with the following commands:
./configure
make
make check
sudo make install
Everything went fine and the library installed correctly. I have created a smple .c file with a text editor and tried to include the <jansson.h> file. I builded everything and it gave no errors, meaning that the library is installed on my system.
Now, Xcode doesn't find the library at all, saying that <jansson.h> is not found. I have tried to restart my Mac, but nothing happens. If anyone knows a possible solution, I will be grateful. Thanks!
I resolved the issue, by going under Build phases, and searching for HEADER_SEARCH_PATH. Then I changed the search path label with /usr/local/include, where the library was installed.
I'm new to OSX and XCode and I'm trying to statically link to a C app. I downloaded and installed libconfig and I link to the installed libconfig.a. It works great on my machine but when I run my binary on another machine I get an error that says libconfig.dylib can't be found. Naturally, I don't want to have to install libconfig everywhere I use my app.
I've scoured through the xcode build settings and the only reference I see is the one for libconfig.a. What am I doing wrong?
I got this to work. This seems to be a libconfig build issue, maybe expected behavior but it surprised me. I was linking to libconfig.a, but it appears that libconfig.a was linking to libconfig.dylib. I reconfigure libconfig and reinstalled it.
./configure --disable-shared
make clean
make
make install
