Managed to get the code compiled.
Perl is installed however the XML::Parser module called up in the
generate_lscp_shell_reference.pl script line 15.
After installing this module and re-running the script directly the build
proceeded until RTMath.cpp.
I am compiling this on a Raspberry PI 4 - ARM processor obviously, the
attached patch as I used the first time I compiled the code some months ago
was required. I had thought it may have by now been applied in the current
source:
cd src/common/
cp atomic.h atomic.h.org
cp RTMath.cpp RTMath.cpp.org
patch -p2 <../../linuxsampler-armv7l.patch
One issue I do have is an error signing the package, this has not been an
issue with the packages but I'd like to know how to fix it perhaps using my
own gpg key. (I have obscured your email address here):
signfile linuxsampler_2.2.0_armhf.buildinfo
gpg: skipped "Christian Schoenebeck <....@users.sourceforge.net>": No
secret key
gpg: dpkg-sign.0v6yB9ud/linuxsampler_2.2.0_armhf.buildinfo: clear-sign
failed: No secret key
Thanks for the help, doubtless I will have further questions.
