I am trying to run a flask app on an apache server so I am using mod_wsgi to deploy it. I downloaded python 3.4 from source and compiled it and it runs just fine. Now I did this:
cd
wget http://modwsgi.googlecode.com/files/mod_wsgi-3.4.tar.gz
tar -zxf mod_wsgi-3.4.tar.gz
cd mod_wsgi-3.4
sudo ./configure --with-python=/usr/local/opt/python-3.4.1/bin/python3.4
make
But when I run make I get this error chain:
/usr/bin/apxs2 -c -I/usr/local/opt/python-3.4.1/include/python3.4m -DNDEBUG mod_wsgi.c -L/usr/local/opt/python-3.4.1/lib -L/usr/local/opt/python-3.4.1/lib/python3.4/config -lpython3.4 -lpthread -ldl -lutil -lm

And I just don't know what to make of it. And ideas?

I'm trying to integrate the compilation of my source code into my recipe in yocto.
When I extract the yocto toolchain and compile myself it works.
Here is the compiler and my makefile in this case:
echo $CC
aarch64-poky-linux-gcc -mcpu=cortex-a72+crc+crypto -fstack-protector-strong -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security -Werror=format-security --sysroot=/home/norian/Yocto/sysroots/aarch64-poky-linux
CFLAGS = -g -Wall -O
INCLUDES = -I /home/norian/Yocto/build-rpi/tmp/work/raspberrypi4_64-poky-linux/radio-image/1.0-r0/recipe-sysroot-native/usr/include/python3.8
LIBS = -lrt -lpthread -lpython3.8
SRCS = main.c config_radio.c
OBJS = $(SRCS:.c=.o)
MAIN = radio
.PHONY: depend clean
all: $(MAIN)
#echo radio has been compiled
$(MAIN): $(OBJS)
$(CC) $(CFLAGS) $(INCLUDES) -o $(MAIN) $(OBJS) $(LFLAGS) $(LIBS)
.c.o:
$(CC) $(CFLAGS) $(INCLUDES) -c $< -o $#
clean:
$(RM) *.o *~ $(MAIN)
depend: $(SRCS)
makedepend $(INCLUDES) $^
But if I try to compile my source code from a yocto recipe I get this error:
| /home/norian/Yocto/build-rpi/tmp/work/raspberrypi4_64-poky-linux/radio-image/1.0-r0/recipe-sysroot-native/usr/include/python3.8/Python.h:44:10: fatal error: crypt.h: No such file or directory
| 44 | #include <crypt.h>
So to correct this I modify INCLUDES in my makefile :
INCLUDES = -I /home/norian/Yocto/build-rpi/tmp/work/raspberrypi4_64-poky-linux/radio-image/1.0-r0/recipe-sysroot-native/usr/include/python3.8 -I /home/norian/Yocto/build-rpi/tmp/work/raspberrypi4_64-poky-linux/radio-image/1.0-r0/sdk/image/usr/local/oe-sdk-hardcoded-buildpath/sysroots/aarch64-poky-linux/usr/src/debug/libxcrypt/4.4.15-r0/build
But then I get the following error:
| aarch64-poky-linux-gcc -mcpu=cortex-a72+crc+crypto -fstack-protector-strong -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security -Werror=format-security --sysroot=/home/norian/Yocto/build-rpi/tmp/work/aarch64-poky-linux/radio-makefile/1.0-r0/recipe-sysroot -g -Wall -O -I /home/norian/Yocto/build-rpi/tmp/work/raspberrypi4_64-poky-linux/radio-image/1.0-r0/recipe-sysroot-native/usr/include/python3.8 -I /home/norian/Yocto/build-rpi/tmp/work/raspberrypi4_64-poky-linux/radio-image/1.0-r0/sdk/image/usr/local/oe-sdk-hardcoded-buildpath/sysroots/aarch64-poky-linux/usr/src/debug/libxcrypt/4.4.15-r0/build -o radio main.o config_radio.o -lrt -lpthread -lpython3.8

Can you explain to me this problem and how to solve it please ?
The configure script for nginx/unit fails because it is not able compile python extension code shown below:
#include <Python.h>
int main() {
Py_Initialize();
return 0;
}
I am using python3.10 which is compiled with openssl-1.1.1.
The compilation gives several symbol not found error including "OPENSSL_sk_num". It seems the symbol is in libcrypto which I have linked in the compile command manually.
Do I need to compile Python again so as to statically link libcrypto and libssl in libpython.a? Below is the full compile command.
cc -pipe -fPIC -fvisibility=hidden -O -W -Wall -Wextra -Wno-unused-parameter -Wwrite-strings -fstrict-aliasing -Wstrict-overflow=5 -Wmissing-prototypes -Werror -g -I/home/shared/Builds/Python-3.1

ds/Python-3.10.0/lib -lcrypto -lssl -lpython3.10 -lpthread -lutil -lm -lm
Luckily, found the fix. Following works -- not sure why
cc -pipe -fPIC -fvisibility=hidden -O -W -Wall -Wextra -Wno-unused-parameter -Wwrite-strings -fstrict-aliasing -Wstrict-overflow=5 -Wmissing-prototypes -Werror -g -I/home/shared/Builds/Python-3.10.0/include/python3.10 -I/home/shared/Builds/Python-3.10.0/include/python3.10 -o build/autotest build/autotest.c -L/home/shared/Builds/Python-3.10.0/lib/ -lpython3.10 -lpthread -lutil -lm -L/usr/local/lib/eopenssl11 -lssl -lcrypto
-lpython3.10 has to precede before -lssl which precedes -lcrypto.

I found out it is using GCC w.r.t to OS but i want GCC of conda to be used for the installation.
pip install psycopg2-binary.tar.gz (Offline installation)
So I am trying to install Pyv8 by following instruction from https://andrewwilkinson.wordpress.com/2012/01/23/integrating-python-and-javascript-with-pyv8/
sudo aptitude install scons libboost-python-dev
svn checkout http://v8.googlecode.com/svn/trunk/ v8
svn checkout http://pyv8.googlecode.com/svn/trunk/ pyv8
cd v8
export PyV8=`pwd`
cd ../pyv8
python setup.py build
sudo python setup.py install
Error comes when running second last command about building the setup.

It is because the version of gcc and g++ is too low for me, as I downgrade it when i install cuda sometime. Just follow the following commands:
$ cd /usr/bin
$ rm gcc
$ ln -s gcc-5 gcc
$ rm g++
$ ln -s g++-5 g++
Done.
I followed the instructions from this link - http://ubuntuforums.org/showthread.php?t=1480282#post_11247864
and installed the libboost_thread package which solved the problem. Thank you https://stackoverflow.com/users/440558/joachim-pileborg

I've run:
sudo apt-get install mysql-server mysql-client python-mysqldb libmysqlclient-dev python-dev
but it didn't help.
The problem was that libmysqlclient.so didn't have symlinks described in https://github.com/javer/gentoo-overlay/issues/4#issuecomment-30748799
For me on Centos, the problem was that MySQL-python did not provide the libmysqlclient_r.so but it had the other numbered versions. By uninstalling it and installing Percona-SQL-devel instead, python was able to find the library and build wheel correctly.
