When installing spaCy under Ubuntu, but I got the following compile error.
The installation code is simply using pip install spacy.
/opt/rh/devtoolset-2/root/usr/bin/gcc -pthread -fPIC -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -I/mnt/nfs/lijin/local/opt/include/python2.7 -I/tmp/pip-install-ikyFEg/spacy/include -I/mnt/nfs/lijin/local/opt/include/python2.7 -c spacy/parts_of_speech.cpp -o build/temp.linux-x86_64-2.7/spacy/parts_of_speech.o -O2 -Wno-strict-prototypes -Wno-unused-function
unable to execute '/opt/rh/devtoolset-2/root/usr/bin/gcc': No such file or directory
error: command '/opt/rh/devtoolset-2/root/usr/bin/gcc' failed with exit status 1
My system has a /usr/bin/gcc but not in /opt/rh/xxx. Can anyone help fix this problem? Thank you.

I am trying to run a GitHub repository that is about SNNs. But, when I run the python script, I get a compiler error from the weave package.
Link: https://github.com/djsaunde/lm-snn/blob/master/code/train/csnn_pc_mnist.py
The code generates neuron groups and after that tried to apply STDP backpropagation algorith to them but brian.STDP object couldn't be generated beacuse of the compiler error.

When pip-installing a Python project with C++ parts,
pip3 install . --verbose --user
the typical compile line will be something like
x86_64-linux-gnu-gcc -pthread -DNDEBUG -g -fwrapv -O2 -Wall -g -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -fPIC -I/usr/include/eigen3/ -I/usr/local/include/python3.7 -I/home/nschloe/.local/include/python3.7m -I/usr/include/python3.7m -c src/generate.cpp -o build/temp.linux-x86_64-3.7/src/generate.o
Explicitly setting CFLAGS like
OPT="" CFLAGS="" pip3 install . --verbose --user
results in
x86_64-linux-gnu-gcc -pthread -DNDEBUG -g -fwrapv -O2 -Wall -Wdate-time -D_FORTIFY_SOURCE=2 -fPIC -I/usr/include/eigen3/ -I/usr/local/include/python3.7 -I/home/nschloe/.local/include/python3.7m -I/usr/include/python3.7m -c src/generate.cpp -o build/temp.linux-x86_64-3.7/src/generate.o
retaining most of the flags.
Question: Where are all the compiler options set? More specifically: How can I remove -g? (It's eating too much memory.)

I know there are many posts with the same python.h error but my problem is the Linux image I have can't run sudo or apt commands
I need to setup python-dev environment onto my Linux image running on Galileo board.
Link to the Linux dev-tools image I'm using is here below.

p.s. it has gcc and python2.7 already.
I'm trying to compile Python 2.7.3 on Centos6. Almost everything works ok, except the thing I really need ^^.
When I type make, I'm getting the error:

And at the end I'm getting a message that the build failed for module _ssl (something like this).
Have you ever faced this problem? I have installed both OpenSSL (0.9.8e fips) and OpenSSL-dev.
Make sure the right paths to openssl-dev (lib and include) are in your Makefile
I am trying to install the fabric library to an old machine. There are some legacy libraries in /usr/lib, such as libgmp.
(py27)[qrtt1#hcservice app]$ ls /usr/lib|grep gmp

libgmp.so.3
libgmp.so.3.3.3
libgmpxx.a
libgmpxx.so
libgmpxx.so.3
libgmpxx.so.3.0.5
I have compiled the libgmp 5.x in my $HOME/app, and then am trying to install pycrypto (it is the dependency of fab):
CFLGAS=-I/home/qrtt1/app/include LDFLGAS=-L/home/qrtt1/app/lib pip install pycrypto
I observed that none of my include or lib directories are in the in the compilation / linking options:

How do I assign the CFLAGS and LDFLAGS correctly for building pycrypto ?
I try to download pycrypto-2.5 and install it:
(py27)[qrtt1#hcservice pycrypto-2.5]$ CFLGAS=-I/home/qrtt1/app/include LDFLGAS=-L/home/qrtt1/app/lib python setup.py install
No CFLAGS or LDFLAGS set up with it. May be the pycrypto-2.5 going wrong ?
Please check what you have typed :
CFLAGS=-I/home/qrtt1/app/include LDFLAGS=-L/home/qrtt1/app/lib pip install pycrypto
it should be CFLAGS
