Problem to compile source code with openSuSE 15.0

[M158m15]

hello community,
to compile the souce code of FreeFileSync was not possible for me. What did I make wrong ? What does not work with SuSE 15.0 ? First I did download the newest version of FFS 10.9. Then I did extract it to my download directory.

 srv15:/home/han/Downloads/FreeFileSync/Source # cat /etc/os-release
NAME="openSUSE Leap"
VERSION="15.0"


Then I tried to compile it. But it does not work at all. Does anybody know what I made wrong ?

The obvious errors I see include

/bin/sh: wx-config: Kommando nicht gefunden.
No package 'openssl' found
No package 'libcurl' found


And the similar ones.
To compile something from source code, you need to provide the development headers of the dependencies. Obviously here, the dependencies include openssl and libcurl. I don't know how openSuSE names their packages, and distrowatch doesn't list the development packages (link) so you will want to check for openssl-dev or openssl-devel (or possibly even libssl-dev) in your package manager. wx-config comes from a wxGTK-devel package or similar.

For my complete buildrequires on Fedora:

BuildRequires: boost-devel
BuildRequires: compat-wxGTK3-gtk2-devel
BuildRequires: desktop-file-utils
BuildRequires: gcc-c++
BuildRequires: ImageMagick
BuildRequires: pkgconfig(gtk+-2.0)
BuildRequires: pkgconfig(libselinux)
BuildRequires: pkgconfig(zlib)
BuildRequires: libcurl-devel %{min_libcurl}
BuildRequires: libssh2-devel %{min_libssh2}
BuildRequires: wxGTK-devel
BuildRequires: %{scl_buildreq}
BuildRequires: openssl-%{name}-devel %{min_openssl}
BuildRequires: openssl-devel


Source: my own Centos/Fedora rpm spec
I confess I don't quite understand the pkgconfig() components. I think basically it is an attribute of whichever is the development header package of the named package, i.e., the zlib-devel rpm has an attribute: "Provides: pkgconfig(zlib)." The names in Fedora are fairly straightforward and this should get you on your way to finding the right packages in openSuSE.

wx-config acts similar to pkgconf --libs, and I'm pretty sure is included in Fedora's wxGTK-devel.

Ah-ha! I found an openSUSE rpm spec file which should be incredibly useful here, albeit it was for FreeFileSync 10.7 so you'll need to add the openssl-dev and libssh2-dev and libcurl-dev.

hello bgstack15
thank you so much for your help.
I did follow your suggest and downloaded from the suse repositories the FFS rpm file.
the installation of this rpm-file on my opensuse 15.0 was successful.
just for fun -- the compilation of the source code is still not working, but the amount of errors
did decrease enormous.

I had a vaguely similar issue on Devuan regarding the "(something) is not a member of `std`" error. I think it has something to do with the way that distro packaged the C++ standard libraries. Check out https://stackoverflow.com/a/52570365/3569534.
Relevant bits, in case the link dies:

Add #include <cstddef> into serialize.h and ring_buffer.h

cd ../../zen/
grep -q -F '<cstddef>' serialize.h || sed -i '1s/^/#include <cstddef>\n/' serialize.h
grep -q -F '<cstddef>' ring_buffer.h || sed -i '1s/^/#include <cstddef>\n/' ring_buffer.h
