It seems since Ghostscript 9.18 e_Fatal e_ExecStackUnderflow e_NeedInput are missing (and many more). Those existed in Ghostscript 9.16 as follows: --------------------------------------------------------------------------- $ egrep 'define e_Fatal|define e_ExecStackUnderflow|define e_NeedInput' \ ghostscript-9.16/psi/ierrors.h #define e_Fatal (-100) #define e_ExecStackUnderflow (-104) #define e_NeedInput (-106) --------------------------------------------------------------------------- In Ghostscript 9.18 those error defines do no longer exist. A diff of psi/ierrors.h between Ghostscript 9.16 and Ghostscript 9.18 shows that many such error defines do no longer exist. Currently I do not know hwy they are dropped in Ghostscript 9.18. As a consequence in the openSUSE Build Service with Ghostscript 9.18 plus the fix for http://bugs.ghostscript.com/show_bug.cgi?id=696301 libspectre build fails currently with --------------------------------------------------------------------------- spectre-gs.c: In function 'critic_error_code': spectre-gs.c:46:9: error: 'e_Fatal' undeclared (first use in this function) case e_Fatal: ^ spectre-gs.c:46:9: note: each undeclared identifier is reported only once for each function it appears in spectre-gs.c:51:9: error: 'e_ExecStackUnderflow' undeclared (first use in this function) case e_ExecStackUnderflow: ^ spectre-gs.c: In function 'spectre_gs_process': spectre-gs.c:112:20: error: 'e_NeedInput' undeclared (first use in this function) error = error == e_NeedInput ? 0 : error; ^ --------------------------------------------------------------------------- At least e_NeedInput is still mentioned for Ghostscript 9.18 in doc/API.htm and doc/Develop.htm and it is used in toolbin/halftone/gen_stochastic/gen_stochastic.c
The PS interpreter errors were amalgamated with the errors in the graphics library (gserrors.h). We felt that two separate lists of error code that had to stay synchronized was a disaster waiting to happen. e_ExecStackUnderflow == gs_error_ExecStackUnderflow e_Fatal == gs_error_Fatal e_NeedInput == gs_error_NeedInput Note that gserrors.h was erroneously left out of the installed files, so you'll want to pick up this commit to ensure it's available: http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=feafe5e5 You could, as an interim measure, add: #define e_ExecStackUnderflow gs_error_ExecStackUnderflow #define e_Fatal gs_error_Fatal #define e_NeedInput gs_error_NeedInput But I would strongly urge that be no more than an interim measure, since we'll be moving forward using the "gs_error_*" style error codes. I'll fix the remaining references to the "e_" style codes shortly.
Chris, many thanks for your prompt reply! I know about http://bugs.ghostscript.com/show_bug.cgi?id=696301 and I have your fix for it in the openSUSE Ghaostscript 9.18 (see my initial comment#0).

No problem, sorry for the confusion. I actually (when I made those changes to the errors) thought that ierrors.h had been deprecated for some time, but I can't now find a reference for that - had I not thought that, I'd have been more conservative and given more notice of the change. Anyway, I believe the remaining references to the "e_*" style errors are removed with this commit: http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=6b1b1d72e
