Unable to build 2.4.1 for 32 bit

[muflone]

Hi

I'm unable to build BG 2.4.1 for x86 32 bit CPU. The build process dies with the error:

 4:50.37 In file included from /build/bluegriffon/src/mozilla-central-c0d35b1c5ab5/bg/ipc/chromium/Unified_cpp_ipc_chromium0.cpp:110:0:

From the project home page it seems clear the 32 bit support was dropped. Does this mean that since 2.4.1 we cannot build BG anymore for 32 bit CPU?

Well. Mozilla says:

• for Linux "As of early 2015 it is no longer possible to do a full build of Firefox from source on most 32-bit systems; a 64-bit OS is required. "
• for Windows "You can still build 32-bit Firefox on a 64-bit Windows installation."
• for OS X, they say nothing so it could still work but I did not test it since Universal Binaries are not supported any more

Closing. https://github.com/therealglazou/bluegriffon/blob/master/config/mozconfig.win contains everything for w32 builds ; linux 32Bits remains unsupported.
