cairo.h build errors

[yiids]

Hi. Im getting build errors. Im on debian 10. I downloaded openframeworks and place lpmt in the apps/myapps folder. errors: In file included from /home/y/src/visuals/of_v0.11.0_linux64gcc6_release/libs/openFrameworks/ofMain.h:65, from /home/y/src/visuals/of_v0.11.0_linux64gcc6_release/apps/myApps/lpmt/src/main.cpp:1: /home/y/src/visuals/of_v0.11.0_linux64gcc6_release/libs/openFrameworks/graphics/ofCairoRenderer.h:4:10: fatal error: cairo.h: No such file or directory

I have libcairo installed: ii libcairo2:amd64 1.16.0-4 amd64 Cairo 2D vector graphics library

if I do the same on openframeworks 0.10 it does build.

btw, the reason I tried with OF 0.10 is because building with 0.11 gives me segfaults: Starting program: /home/y/src/visuals/of_v0.10.1_linux64gcc6_release/apps/myApps/lpmt/bin/lpmt_debug [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Looks like none of these errors are LPMT specific, they are related to building OF. 0.10.1 and 0.11.0 are different beasts build wise.

You might have libcairo2, but you probably need libcairo2-dev. check that you have that.

Always run the install_dependencies.sh script on Linux when switching to a new version of OF. On debian it can be found here: openFrameworks/scripts/linux/debian/install_dependencies.sh You'll need to run it using sudo.

Try that and get back to me.

[yiids]

I ran the script and all dependencies are installed, including libcairo-dev. I have /usr/include/cairo/cairo.h

[pierrep]

Are you able to build other OF apps?

[yiids]

one of the commits of the last two days somehow fixed the problem, now it builds without errors on OF 0.11

[pierrep]

I can't really see how any of my recent commits would have any impact on the build process, but glad that you have it fixed. I did a bunch of work last week that has improved lots of things!
