Doesn't build on i386

[trebmuh]

Hi @brummer10 , trying to build on a Debian Buster on a i386 chroot, it gives me the following:

g++ -g -O2 -fdebug-prefix-map=/build/xmonk.lv2-0.4=. -fstack-protector-strong -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 -I. -I./dsp -I./plugin -fPIC -DPIC -O2 -Wall -funroll-loops -fstack-protector -ffast-math -fomit-frame-pointer -fstrength-reduce -fdata-sections -Wl,--gc-sections -Wl,-z,relro,-z,now -Wl,--exclude-libs,ALL -msse3 -mfpmath=sse plugin/Xmonk.cpp  -Wl,-z,relro -I. -shared -lm -Wl,-z,noexecstack -fvisibility=hidden -o Xmonk.so

Any idea maybe?

Could you try please with -mfxsr added to the CXXFLAGS in the makefile.
I don't have a i386 box, so I only guessing.

[trebmuh]

That did the trick.
I mean, with adding -mfxsr to the CXXFLAGS in Xmonk/Makefile, it built on a Debian Buster i386 chroot here, note that I didn't test the resulting binary on a i386 system, just it built (tm).
Thank you very much @brummer10 , closing here now.

[brummer10]

Thank you for trying. So I could add a fix for this in general to all affected projects.
btw. you are aware of this one: https://github.com/brummer10/GxMatchEQ.lv2
as it use the same denormalize technic then this one here.

[trebmuh]

I'm not! Usually, I'm only using/packaging Guitarix and the GXplugins suite (plus screcord, gxtuner, and jalv.select). Is this GXmatchEQ supposed to be incorporated into the GXplugins at a later point? The reason I'm asking is because, I would probably avoid to package it for LZK if it is expected to join the GXplugins family (it's a bit of a pain to manage this king of transition).
BTW: do you have other plugins/project LA-related maybe?

[brummer10]

No, it will not join the GxPlugins suite. all GxPlugins been suited for the MOD, that is not the case for GxMatchEQ.
I've some other projects LA related, but nothing worse to package. So when you take that one, you'll have all worse to keep a eye on it. Note, for now it will have the same issue as this one here, I need to push a fix latter on.

[trebmuh]

OK, thanks for the time you took for that. I'll look at packaging this GxMatchEQ for LZK soon-ish.

Hi @brummer10 , just came back reading at this one.
It does seem that the "mfxsr" thingy has not made it into the master code here. Is that on purpose?

[brummer10]

Yea, I've forgotten about it. Should be fixed now with the latest commit.
