C compiler cannot create executables

[imesg]

First six packages failed with this error.

Need help with this.

What info can I provide?

make.conf.lto and make.conf.lto.defines are largely unchanged.

Below are the changes I made to make.conf to get started. But immediately encountered the 'cannot create executables' problem.

Thanks

Here is the error:
CFLAGS="-march=native ${CFLAGS} -pipe" # -falign-functions=32" #NOTE: Consider using -falign-functions=32 if you use an Intel processor. See issue #164.

Too many quotes.

Fix:

NTHREADS="4" #REPLACE WITH NUMBER OF CORES
CFLAGS="-march=native ${CFLAGS} -pipe -falign-functions=32"
#CXXFLAGS="${CFLAGS}"
#FCFLAGS="${CFLAGS}"
#FFLAGS="${CFLAGS}"

MAKEOPTS=${NTHREADS}

USE="cups graphite gphoto2 ieee1394 lto wayland -multilib -smartcard"

How's your make.conf.lto and make.conf.lto.defines look? I was running flto= was the longest time because I didn't define $NTHREADS.

I still have the same problem as before.

Here are my make.conf* files.

Thanks for help.

Are you making new lines for each USE flag? I believe that doesn't work. If you want it to be easier to read, you can do something like:

KDEUSE="qt5 kde systray"
OPTIMIZATIONSUSE="pgo lto"

USE="${KDEUSE} ${OPTIMIZATIONSUSE}"

Been doing it for years. Seems to work ok. Easier to read that way. Cut and paste doesn't show the back slashes for some reason. There is a back slash after every line allowing continuation on the next line.

I continue to have the 'cannot create executable' problem.

Seems a reboot was all that was needed.
