Arch Linux User Repository

To get the package building I had to remove "freerdp" (version 3), install "freerdp2" (via AUR) and add

export CFLAGS="$CFLAGS -Wno-error"

right before the ./configure ... line in the PKGBUILD

export CFLAGS="$CFLAGS -Wno-error=macro-redefined"

might also work, but I did not test this

If I try to build in clean chroot, it also quits because the dependencies are not present in the repo:

==> Checking buildtime dependencies...
==> Installing missing dependencies...
error: target not found: libtelnet
==> ERROR: 'pacman' failed to install missing dependencies.
==> Missing dependencies:
  -> libvncserver
  -> libtelnet
==> ERROR: Could not resolve all dependencies.
==> ERROR: Build failed, check /var/lib/archbuild/multilib-x86_64/alicn/build

Getting the same:

Is it just me that's getting this error during build?

@sanbikappa thanks. Patch added.

@lowlow
please refer: GUACAMOLE-2070
As a workaround, you can revise prepare() in PKGBUILD:

prepare() {
    cd "$srcdir"/$pkgname-$pkgver
    # refer: https://github.com/apache/guacamole-server/pull/591
    curl -O https://raw.githubusercontent.com/mike-jumper/guacamole-server/2e2a33621d673345e7b9d22c9388be80c6d77598/src/libguac/wol.c
    mv -f wol.c src/libguac/wol.c
}

I failed to build the last version (1.6.0) of the server. Here is the issue I get:

    inlined from '__guac_wol_send_packet' at wol.c:104:18,

Hi Figue,

Thank you for continuing to build the package even though you no longer use it yourself!

Klaus.

I'm not using guacamole anymore, but I'll try to keep maintaining if there isn't any volunteers.

@dodecahedron freerdp is an optional dependency, so if you install freerdp2 and rebuild, it should work out-of-the-box. I'll updated anyway the optdepend array in order to point the user to the right package.

About patching service files: I prefer to avoid it. Perhaps is a better choice send an email upstream or file a bug.

Thanks for reporting.
