I wanted to play around with this lattice fpga "go board" I've had laying around When I got sent the lattice IDE "iCEcube2" installer it failed to launch on my ubuntu 22 machine :/. Apparently it's only supposed to run on red hat... For me I was failing to link with libpng12 which was not available in my ubuntu repos. I based on this answer I just wget'd the source.

wget https://ppa.launchpadcontent.net/linuxuprising/libpng12/ubuntu/pool/main/libp/libpng/libpng_1.2.54.orig.tar.xz

I had a little trouble configuring it to build for 32 bit but

CFLAGS="-m32" LDFLAGS="-m32" ./configure

did the trick. Then I was also missing libSM.so but that was easily done with apt

sudo apt install libsm-dev:i386

After that looking at

ldd ./iCEcube2setup

showed no missing libraries and was able to launch. Today is March 27, 2025
