SkyScraper not building

[Subtixx]

Somehow the -fno-lto doesn't work for me:

Could not successfully build skyscraper - Scraper for EmulationStation by Lars Muldjord (/home/subtixx/apacman/ArchyPie-Setup/tmp/build/skyscraper/Skyscraper not found).
/home/subtixx/apacman/ArchyPie-Setup

Manually executing the compile with -fno-lto removed does compile though.

[V0rt3x667]

Thanks for checking out the script and reporting the bug. I will look into this and get back you asap.

[V0rt3x667]

Hello, I built Skyscraper on Arch Linux and I can see that LTO is enabled by default. I am using a Gen 3 Intel i5 CPU on a laptop and the build time seemed reasonably quick even with LTO enabled. Is there any particular reason it needs to be disabled for you? I am guessing it causes issues on a Raspberry Pi. Please confirm, thank you.

[Subtixx]

No no you must've misunderstood me.

1. Not using a Raspberry Pi^^ Using an Intel Xeon Machine. Also I'm using EndeavourOS btw.
2. Its not that I want lto disabled. but as you can see at the command line it uses 2 different arguments:

-fno-lto [...] -flto=4 -fno-fat-lto-objects

this causes a huge problem while compiling. Since it doesn't generate lto files but the linker then requires LTO files..

And no I have no idea where -fno-lto comes from its a clean Endeavour install with only Archypie installed. All I can say is that using the same command line as the script but removing -fno-lto results in SkyScraper successfully building.

[V0rt3x667]

Thanks for clarifying. I don't get that issue in Arch Linux see below snippet. Just to confirm does EndeavorOS use GCC 12 by default?

g++ -c -pipe -std=c++11 -march=native -mtune=native -pipe -O2 -flto -fno-fat-lto-objects -Wall -Wextra -D_REENTRANT -fPIC -DVERSION=\"3.7.7\" -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_NETWORK_LIB -DQT_XML_LIB -DQT_CORE_LIB -I. -I. -I/usr/include/qt -I/usr/include/qt/QtGui -I/usr/include/qt/QtNetwork -I/usr/include/qt/QtXml -I/usr/include/qt/QtCore -I. -I/usr/lib/qt/mkspecs/linux-g++ -o moc_fxbrightness.o moc_fxbrightness.cpp

[Subtixx]

Yes it uses gcc 12.2.1:

Thats weird. I have no idea where this -fno-lto comes from.

[V0rt3x667]

Yes it is strange how that flag has crept in there. I will see what I can find out. I confess I have yet to use EndeavorOS but this gives me an excuse to try it out.

[V0rt3x667]

I tested ArchyPie in a clean EndeavourOS build, No DE installed. I built the core modules (Retroarch, EmulationStation etc) and then built Skyscraper. I did not have any issues and the -fno-lto flag was not present. Do you recall building any other modules from ArchyPie or any software from the AUR prior to building Skyscraper? It is possible the stray -fno-lto flag could have been introduced by an export command in another module.

[Subtixx]

The only thing I installed before ArchyPie was the fish shell nothing else

[V0rt3x667]

I setup Fish to run as an interactive shell by adding exec fish to my .bashrc file. I rebooted EOS, launched the archypie-setup script and compiled Skyscraper with no issues and again the -fno-lto flag was not present.

I don't have a Xeon CPU to test with in case there is some instruction set that changes the compilation behaviour under GCC.

[V0rt3x667]

Hi, could you please advise me if you are still having issues with building Skyscraper? Thanks

[V0rt3x667]

Closing. I could not replicate the issue.
