Build fails on linux

[Joefish]

Linux Fedora 5.1.15-300.fc30.x86_64, mono 5.18.1.3, glibc 2.29

I try to compile Mesen from master[373c489] and it fails with

cd UpdateHelper && msbuild /property:Configuration="Release" /property:Platform="AnyCPU"
/bin/sh: msbuild: command not found
make: *** [makefile:91: ui] Error 127

Apparently msbuild doesn't ship as an indepenent binary anymore (at least for linux) and dotnet build should be used. After substituting the command in the makefile I get the following

cd UpdateHelper && dotnet build /property:Configuration="Release" /property:Platform="AnyCPU"

download and install msbuild sepately, this is not part of mono package in recent releases....

[Joefish]

Still the same error

Just wondering, is it actually supposed to look for .netv4.5 on linux?
Maybe the build is mixing up platforms?

[SourMesen]

Unfortunately it looks like there are 2 different "msbuild" tools, and they are not equivalent.

Running msbuild /version (it needs to be a slash, not a dash) should give you something like this:

Microsoft (R) Build Engine version 15.6.0.0 ( Fri Apr  6 15:55:10 UTC 2018) for Mono
Copyright (C) Microsoft Corporation. All rights reserved.

Someone else had the same issue recently and the fix was to install the right "version" of msbuild.

(Edit: the important bit is for Mono vs for .NET Core in what you posted earlier)

[Joefish]

After failing to compile msbuild for hours I just realized mono has packages for Fedora on their website..
You are right, that fixed it. Now I have a different error though, that it can't find libgdiplus.so.0 (I checked and it's there in /usr/lib64)

[SourMesen]

Is that while compiling the code, or when trying to run the application?
If compiling, that would be pretty odd.
If at runtime, that message is usually a sign that something is broken in the Mono installation (e.g maybe the part of mono that implements WinForms is not installed properly, or not installed at all, etc)

Also, since you seem to have installed (at least parts of) .NET Core earlier, it's not impossible that the libgdiplus library you're seeing is .NET Core's rather than Mono's, etc.

[Joefish]

So, I now deinstalled .net core, reinstalled everything mono to make sure that it downloads from the correct repo, and installed libgdiplus manually from the mono repo, still the same.
But it is a problem with my system, not with mesen install scripts as it even crashes for a simple hello world that uses Windows.Forms.
I got an interesting log from it though

Apparently it doesn't find the 'GifQuantizeBuffer' symbol.
Check linked libs of libgdiplus -- libgif.so available
Check symbol table of libgif -- no GifQuantizeBuffer ....
Yeah, so between 5.19 and 5.20 [befe18877] it was moved to a util lib that now explicitly needs to be linked if you want support for it. Of course Fedora doesn't do it so everything that depended on it and didn't roll libgif on it own and statically linked it is fucked now. Downgraded to 5.1.4, everything working smooth now. Took me only hours to figure this out..

I will try to talk to the fedora package people about it as I have seen a few posts describing similiar problems with mono and gdiplus.
Edit: Just found libgdiplus is also on github and it already has an issue for it.
Also on the gentoo bugtracker

[SourMesen]

Thanks for the investigation and reporting on it. Hopefully this helps out someone else with the same issue someday. Glad you got it working in the end!

[scottlinux]

@Joefish Thank you! I have had the same issue on Fedora 30. Rock on,
