After Pill Nr. 12.5 Completing graphviz with gd - still failing with: 'Format: "png" not recognized use one of canon [...]'

[ThoenigAdrian]

[jane@nixos:~/graphviz]$ nix-build graphviz.nix 
/nix/store/sz5apb4n1sgc6drm819hzwjn0wwqkkzd-graphviz

[jane@nixos:~/graphviz]$ echo 'graph test { a --b }' | ./result/bin/dot -Tpng -o test.png

Format: "png" not recognized. Use one of: canon cmap cmapx cmapx_np dot eps fig gv imap imap_np ismap pic plain plain-ext pov ps ps2 svg tk vml xdot xdot1.2 xdot1.4

If i open a nix-shell this is the output i get:

[jane@nixos:~/graphviz]$ nix-shell graphviz.nix 

[nix-shell:~/graphviz]$ echo $buildInputs
/nix/store/f6y1dzdl0n5rziyrf5859kvgzn2p8ryl-gd-2.2.5-bin /nix/store/7kgppvnhlh66avxl3q4h51qvl0v1970y-fontconfig-2.12.6-bin /nix/store/y0ppnpv6f3cranc4cj4v3hhsy6dj9lfk-libjpeg-turbo-2.0.3-bin /nix/store/iws7dm1jij4lv09mbpwf9i8lc1d4b798-bzip2-1.0.6.0.1-bin

[nix-shell:~/graphviz]$ echo $NIX_LDFLAGS


[nix-shell:~/graphviz]$ source setup.sh 

[nix-shell:~/graphviz]$ echo $NIX_LDFLAGS

[nix-shell:~/graphviz]$ echo $NIX_CFLAGS_COMPILE

It seems fine though I would've expected some paths refering to gd in NIX_LDFLAGS .

Debug output (Feel free to skip if you already know the issue)

Does anyone what's the issue here ? I suspect it might be a problem on my end but i can't find it.

Oh just saw there is already an issue for that: #107
