[SailfishDevel] Building non Qt Libraries (autotools) - Trying to build pocketsphinx (voice recognition library) for Sailfish

[Nicolas Cisco]

I'm trying to build sphinxbase and pocketsphinx for Sailfish, i could find
this topic (
https://together.jolla.com/question/22379/porting-sdl-20-game-to-sailfish/
) which involves building non qt apps, but i'm having some problems.

First of all, i'm using sphinxbase 0.8 and pocketsphinx 0.8 packages which
can be downloaded from here (
http://cmusphinx.sourceforge.net/wiki/download/ ). I could build these
packages without having to make any modifications to the source code.
I'm using these .specs files:

sphinixbase.spec:
    Name: sphinxbase
    Summary: SphinxBase
    Version: 0.8
    Release: 1
    Group: Libraries
    License: LICENSE
    URL: http://example.org/
    Source0: %{name}-%{version}.tar.bz2

    %description
    Short description of my SailfishOS Application

    %prep
    %setup -q -n %{name}-%{version}

    %build
    # Command used to compile the application
    ./autogen.sh --enable-fixed --prefix=/usr/
    make

    %install
    rm -rf %{buildroot}
    # Command used to install files into %{buildroot}
    %make_install

    %files
    %defattr(-,root,root,-)
    %{_bindir}/sphinx*
    %{_libdir}/*
    %{_libdir}/pkgconfig/*
    %{_includedir}/%{name}/*

pocketsphinx.spec:
    Name: pocketsphinx
    Summary: PocketSphinx
    Version: 0.8
    Release: 1
    Group: Libraries
    License: LICENSE
    URL: http://example.org/
    Source0: %{name}-%{version}.tar.bz2
    BuildRequires: pkgconfig(sphinxbase)

    %description
    Short description of my SailfishOS Application

    %prep
    %setup -q -n %{name}-%{version}

    %build
    # Command used to compile the application
    ./autogen.sh --enable-fixed --prefix=/usr/
    make

    %install
    rm -rf %{buildroot}
    # Command used to install files into %{buildroot}
    %make_install

    %files
    %defattr(-,root,root,-)
    %{_bindir}/%{name}*
    %{_libdir}/lib*
    %{_libdir}/pkgconfig/*
    %{_includedir}/%{name}
    %{_datadir}/man
    %{_datadir}/%{name}

Connection to the build engine though ssh, I could build correctly
sphinxbase using this command: `mb2 -t SailfishOS-i486 -s sphinxbase.spec
build`.

Then, i tryed to install this package the build engine, but i couldn't:
    [mersdk at SailfishSDK sphinxbase-0.8]$ sb2 -t SailfishOS-i486 -m
sdk-install -R pkcon install     RPMS/sphinxbase-0.8-1.i586.rpm
    [mersdk at SailfishSDK sphinxbase-0.8]$ sb2 -t SailfishOS-i486 -m
sdk-install -R zypper install     ./RPMS/sphinxbase-0.8-1.i586.rpm
    Loading repository data...
    Reading installed packages...
    '_tmpRPMcache_:sphinxbase=0:0.8-1' not found in package names. Trying
capabilities.
    No provider of 'sphinxbase = 0:0.8-1' found.
    Resolving package dependencies...

    Nothing to do.

If then, i try to build pocketsphinx, i can't, since my .spec file has
pkgconfig(sphinxbase) in the BuildRequires:

    [mersdk at SailfishSDK sphinxbase-0.8]$ mb2 -t SailfishOS-i486 -s
pocketsphinx.spec build
    Fatal: 'pocketsphinx.spec' doesn't exist (and could not be made from a
yaml)

If i comment out the BuildRequires, i'm able to build pocketsphinx with
this command: `mb2 -t SailfishOS-i486 -s pocketsphinx.spec build`. Again,
trying to install the package to the build engine throws me errors:
    [mersdk at SailfishSDK pocketsphinx-0.8]$ sb2 -t SailfishOS-i486 -m
sdk-install -R pkcon install     RPMS/pocketsphinx-0.8-1.i586.rpm
    [mersdk at SailfishSDK pocketsphinx-0.8]$ sb2 -t SailfishOS-i486 -m
sdk-install -R zypper install ./RPMS/pocketsphinx-0.8-1.i586.rpm
    Loading repository data...
    Reading installed packages...
    '_tmpRPMcache_:pocketsphinx=0:0.8-1' not found in package names. Trying
capabilities.
    No provider of 'pocketsphinx = 0:0.8-1' found.
    Resolving package dependencies...

    Nothing to do.

As i can't install pocketsphinx nor sphinxbase, i can't build any
application using this libraries (if i explore /usr/include,
/usr/lib,/usr/lib/pkgconfig, I can't find any sphinx's file).

If i execute pkg-config, i get this output:
    [mersdk at SailfishSDK pocketsphinx-0.8]$ sb2 -t SailfishOS-i486 -m
sdk-install -R pkg-config --libs --cflags pocketsphinx
    Package pocketsphinx was not found in the pkg-config search path.
    Perhaps you should add the directory containing `pocketsphinx.pc'
    to the PKG_CONFIG_PATH environment variable
    No package 'pocketsphinx' found

Sending the rpm packages to the nemo user and then installing them with
`pkcon install-local` gives me a successfull output. In addittion,
pkg-config gives me the correct output:
    [nemo at SailfishEmul ~]$ pkg-config --libs --cflags pocketsphinx
    -I/usr/include/sphinxbase -I/usr/include/pocketsphinx  -lpocketsphinx
-lsphinxbase -lsphinxad -lpthread -lm

I'm a bit lost with this, any help?.
Thanks in advance!
