Addition of a prefix to the names of the libraries

[jvdp1]

Addition of the prefix fortran_stdlib_ to the names of all libraries.

The prefix fortran_stdlib_ is required to avoid conflicts when fortran-stdlib is installed via package managers.

Fixes #1101

[jvdp1]

@zoziha would such an approach solve your issue?

Each library starts now with libfortran_stdblib_.

Here is the Makefile used to test the order of the libraries provided by pkg-config after the installation of stdlib (it should be placed inside example and the variable install_dir should be adapted):

# Necessary if the installation directory is not in PKG_CONFIG_PATH
install_dir :=$(CURDIR)/../../stdlib_make1

export PKG_CONFIG_PATH := $(install_dir)/lib/pkgconfig:$(PKG_CONFIG_PATH)

STDLIB_CFLAGS := `pkg-config --cflags fortran_stdlib`
STDLIB_LIBS := `pkg-config --libs fortran_stdlib`

# Example definition of Fortran compiler and flags
FC := gfortran
FFLAGS := -O2 -g

@fortran-lang/stdlib It might be a good idea to add such a Makefile in a CI workflow for testing pkg-config. The modularization of stdlib leads to a quite complex order of the libraries.

[zoziha]

Thanks for this addition, @jvdp1 .
And I submitted a sub-PR to fix the issue of duplicate exported library names in the fortran_stdlib.pc file.

Thank you @zoziha . Unfortunately your proposed changes breaks the dependency order of the libraries. Based on your comment, I commited the following changes: a106c59 . could you check that it solves your issue re: duplicates, please?

Yes, the duplicate library names are resolved correctly with your commits. LGTM, if there are no new comments, this PR can be merged at any time. Thank you, @jvdp1.

Thank you @zoziha for testing it.
Should we generate a new release (e.g. v0.8.1) such that you are able to package it for MSYS2?

[zoziha]

Should we generate a new release (e.g. v0.8.1) such that you are able to package it for MSYS2?

Yes, this will do me a favour, so that I can easily package the latest fortran_stdlib for MSYS2. Alternatively, I might need to set up a git patch file for the fortran_stdlib package of MSYS2 based on the fortran_stdlib-v0.8.0 tarball and this PR. Both are acceptable.

[jalvesz]

LGTM @jvdp1, I have one question regarding your proposal to include the makefile in the CI. That seems fragile as it might imply tracking manually changes in all modules. Is any way that the makefile or at least the list can be generated in a automatic manner?

Agree for a 0.8.1

I agree with you @jalvesz that the Makefile I pasted above is highly-error prone, and we should not use it in a CI workflow. Actually we don't need a makefile for testing the order generated by pkg-config. The following should be enough if applied to all example f90 files:

gfortran -O2 -g `pkg-config --cflags fortran_stdlib` ascii/example_ascii_to_lower.f90 `pkg-config --libs fortran_stdlib`

I'll think about a more general cross-platform approach
