i686-linux-gnu-gcc: error: unrecognized command line option '-V'

[SimonDanisch]

Not sure if this is an issue with the environment or with ImageMagick:

Good job on the full log; that error isn't the problem, (configure runs a bunch of commands that causes gcc to fail because it's searching for how to pass proper options to it) it's actually the one farther down:

configure:5193: checking whether the C compiler works
configure:5215: /opt/i686-linux-gnu/bin/i686-linux-gnu-gcc   -all-static conftest.c  >&5
i686-linux-gnu-gcc: error: unrecognized command line option '-all-static'
configure:5219: $? = 1
configure:5257: result: no

I'm not sure why it's trying to pass -all-static; I don't think that's a GCC option.

This is a buggy interaction between libtool and autoconf. A workaround was discussed in 2004(!) but I don't believe it was ever implemented. The suggested solution was to run ./configure LDFLAGS=-static; make LDFLAGS=-all-static. I don't know how to implement that in BinaryBuilder, though.

[leo60228]

Horrible hack solution:

#!/bin/sh
WRAPPED_BIN="gcc"
ARGS=("$@")
ARGS=("${ARGS[@]/#-all-static/-static}")
ARGS=("${ARGS[@]/-V}")
"$WRAPPED_BIN" "${ARGS[@]}"

[staticfloat]

Why not just do the ./configure LDFLAGS=-static; make LDFLAGS=-all-static in the builder repository?

[leo60228]

...because I'm an idiot sorry. I'll see if BinaryBuilder works on NixOS first, though. Not sure how to setup Travis on a fork.

[leo60228]

Wait a second. ImageMagickBuilder explicitly specifies -all-static. Why is it doing this? How did this ever work?

[staticfloat]

If I had a nickel for every time I thought that to myself.......

I'll try running it locally without that. Looks like it's a very recent commit that Simon added to try and fix Windows: JuliaIO/ImageMagickBuilder@22377e5

[leo60228]

Wait, there's already a PR for this. Hm. JuliaIO/ImageMagickBuilder#5

[staticfloat]

Confirmed that removing that LDFLAGS export fixes this.

Sorry about this, I just copy & pasted that flag from the imagemagick forums and messed up when trying to make sense of the error log....
