Compiling on Debian 9.8

[tank-trax]

I tried to compile LMMS according to your instructions but was unable to using the following

git clone --recurse-submodules -b master https://github.com/lmms/lmms

these are the steps I used to successfully compile

git clone https://github.com/LMMS/lmms.git
cd lmms/
git submodule update --init --recursive
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=../target/
make -j4

./lmms

Could you check the version of Git you have? Also, please upload error message on the step, if any.

[tank-trax]

git version 2.11.0

I follow these steps

git clone --recurse-submodules -b master https://github.com/lmms/lmms
cd lmms
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=../target/
make -j4

and it fails at

Could you run make without -j4? It will help finding the issue.

installed qtbase5-private-dev and it's moving along...

[lukas-w]

I'm assuming installing qtbase5-private-dev fixed it. Closing as duplicate of #4273.

[tank-trax]

it fixed it however not all modules are building.... papu for example

[zonkmachine]

it fixed it however not all modules are building.... papu for example

You are compiling master and papu has changed name in master to freeboy. What message do you get about papu when compiling?

[tank-trax]

it's when I open some of the demos... there are many LADSPA plugins missing

for example

[tank-trax]

I managed to copy over some LADSPA from the git recursive build that fixed the missing errors
also the INITS are causing most if not all of the popping
presets are nice and clean

this build works however is missing some LADSPA plugs that some of the demos use

[tank-trax]

the master build was missing the following:

/lib/lmms/ladspa: calf.so
/lib/lmms/ladspa: ladspa-util.so
/lib/lmms: libOPL2.so
/lib/lmms: libpapu.so
