FTBFS since Lexbor inclusion in urlsource 0.2.1

[flexiondotorg]

URL Source 0.2.1 and 0.2.2 FTBFS.

I build OBS Studio and 50 plugins from source as a portable build for Ubuntu.

Most plugins, including urlsource, are built in the same way. Here is the generic build for a plugin:

• https://github.com/wimpysworld/obs-studio-portable/blob/main/builder/obs-build.sh#L499

A couple of flags are provided for URL Source to prevent compiler warnings from failing the build:

• https://github.com/wimpysworld/obs-studio-portable/blob/main/builder/obs-build.sh#L454

Since Lexbor was included in URL Source 0.2.1, the plugin fails to build from source. Here is the log:

A few weeks ago, I experienced a similar pugixml issue in this project. I worked around it by using a system-provided pugixml.

I cannot use the same workaround for Lexbor as it is not published in Debian/Ubuntu archives.

thanks for the input! there was a thing i had to put in place for Linux so this would work with building Lexbor but i thought i got that fixed... the missing cmake dependency the CI builds it fine on Ubuntu i can look at it on my Ubuntu machine and try to build from source

[royshil]

im able to replicate this on my ubuntu trying to fix it...

[royshil]

@flexiondotorg can you check #55 ? it fixed the problem for me

[flexiondotorg]

@royshil Thanks for working on a fix :bow:

I confirm that building from source using the roy.fix_linux_build_lexbor branch is successful :+1:

[royshil]

fixed on master
