Compile Python3.7 on Solaris 10

Today I've spent some hours fighting with Solaris 10 trying to compile Python3.7 from sources with openSSL support.

The process is quite simple so I'll write it here so it can help someone with the same problem.

pkgadd -d http://get.opencsw.org/now
/opt/csw/bin/pkgutil -U
/opt/csw/bin/pkgutil -y -i libssl_dev
/opt/csw/bin/pkgutil -y -i libssl1_0_0
/opt/csw/bin/pkgutil -y -i libreadline6 
/opt/csw/bin/pkgutil -y -i libreadline_dev 
/opt/csw/bin/pkgutil -y -i libncurses_dev 
/opt/csw/bin/pkgutil -y -i libssl_dev 
/opt/csw/bin/pkgutil -y -i libsqlite3_dev 
/opt/csw/bin/pkgutil -y -i tk_dev 
/opt/csw/bin/pkgutil -y -i libgdbm_dev 
/opt/csw/bin/pkgutil -y -i libbz2_dev 
/opt/csw/bin/pkgutil -y -i libffi_dev 
/opt/csw/bin/pkgutil -y -i tk 
/opt/csw/bin/pkgutil -y -i pkgconfig 
/opt/csw/bin/pkgutil -y -i libsodium_dev # for paramiko
wget https://www.python.org/ftp/python/3.7.6/Python-3.7.6.tgz
gunzip -c Python-3.7.6.tgz | tar xvf -
cd Python-3.7.6

tip: edit Modules/socketmodule.c

         PyErr_Clear();
         if (!PyArg_ParseTuple(args, "O&:sethostname",

To avoid an error related to sethostname.

Also, yo avoid problems with ctypes module you need to add the PKG_CONFIG_PATH option in the configure statement as follow:

  ./configure --prefix=/opt/python3 --with-openssl=/opt/csw/ --enable-optimizations LDFLAGS='-L/opt/local/lib -I/opt/csw/include -L/opt/csw/lib  -R/opt/local/lib' PKG_CONFIG_PATH=/opt/csw/lib/amd64/pkgconfig/ CPPFLAGS='-L/opt/local/lib -I/opt/csw/include -L/opt/csw/lib  -R/opt/local/lib'

 gmake
 gmake install
 PATH=/opt/python3/bin/:$PATH

You won't be able to use pip3 without adding such openssl flag to the configure step. And you need to install exactly the version 1.0.0 of libssl from CSW.

With all of this we will have python3 installed and pip3 working!

If you need to install pandas or numpy or somilar software I would recommend:

/opt/csw/bin/pkgutil -y -i gcc5g++ libffi_dev libssl_dev libbabl_dev cython automake autoconf libsodium_dev jq pkgconfig cswpki libatlas_c++ libatk_dev
pip3 install --upgrade cython
pip3 install pandas

Best regards.

Hi I am attempting this on Solaris 11.4 x86 on an esxi VM in hopes of using letsencrypt with certbot to get free SSL certs. I am building both Python 3.7.10 and 3.9.5 from source (latest stable from python.org). My config and needs are probably different from yours, but if you happen to have any hints, much appreciated. BTW, your writeup is much more straightforward than other stuff I found. Thank you!

I get the following issues:

(1) diff -u ../socketmodule.c Modules/socketmodule.c
What is your current working directory when you start? Mainly because on your step where you call to edit socketmodule.c, you enter the Python subdir and compare your Python sources copy with a copy that you have in the .. directory.

From your diff output, I just assumed that I needed to replace the ifdef in my copy:
#ifdef AIX
extern int sethostname(const char *, size_t);
#endif
with the if referenced in your instructions:
#if (defined(sun) && defined(_SVR4))
extern int sethostname(const char *, size_t);
#endif

(2) Python3.7.10

Wondering what PATH and gcc version was used, as unable to duplicate your success (using Solaris 10 Update 8 on a VirtualBox - Intel)
