I have a 25-page postscript file (available gzipped at <http://www.inference.phy.cam.ac.uk/sanjoy/mpage/dimensional-analysis.ps.gz> that mpage-2.5.3-4 doesn't process right. It produces a postscript file with 0 pages. The vanilla mpage-2.5.3 works fine (I built it from the .tar.gz file using just 'make' and all the defaults). I then applied one patch at a time from the 2.5.3-4 SRPM. The only patch that made it break was mpage-2.5.3-utf8.patch The cmd line that breaks mpage: % ./mpage -b letter -2o < dimensional-analysis.ps whereas if I don't use stdin, it works fine: ./mpage -b letter -2o dimensional-analysis.ps I'm using a Pentium Linux (RH 7.3) system (I built the 2.5.3-4 RPM from the rawhide SRPM and found the problem originally, then tracked down the individual patches). A minor change is that the spec file says the license is BSD but the COPYING file is GPL v2. -Sanjoy Here's a bit more details of what breaks and the command sequence: % printenv MPAGE /* to show that MPAGE is unset */ % rm -fr mpage-2.5.3 % tar xzf mpage-2.5.3.tgz /* reinstall clean sources */ % cd mpage-2.5.3 % make [compiles with no problem] % ./mpage -b letter -2o < dimensional-analysis.ps | grep Pages %%Pages: (atend) %%%Pages: 25 %%Pages: 1 %%Pages: 1 %%Pages: 1 %%Pages: 1 %%Pages: 1 %%Pages: 1 %%Pages: 1 %%Pages: 1 %%Pages: 1 %%Pages: 1 %%Pages: 13 [Like it should be -- 25 pages originally, now 13 2-up pages] [Now I apply the utf8 patch:] % patch -p1 < /usr/src/redhat/SOURCES/mpage-2.5.3-utf8.patch patching file file.c patching file glob.c patching file mpage.c patching file mpage.h patching file text.c % make [All compiles fine except for the warning below:] gcc -O2 -s -DPAGE_DEF=\"A4\" -DLIBDIR=\"/usr/local/share/mpage\" -DDEFAULT_ENCO DING=1 -DDEFAULT_DUPLEX=0 -DDEFAULTSMARGIN=18 -DSPOOLER=BSD_SPOOLER -Wall -c -o file.o file.c file.c: In function `looks_utf8': file.c:547: warning: array subscript has type `char' [Now retry mpage:] % ./mpage -b letter -2o < dimensional-analysis.ps | grep Pages %%Pages: (atend) %%Pages: 0 [Ack! 0 pages in the resulting file!] [And with cmd line input instead of stdin] % ./mpage -b letter -2o dimensional-analysis.ps | grep Pages %%Pages: (atend) %%%Pages: 25 %%Pages: 1 %%Pages: 1 %%Pages: 1 %%Pages: 1 %%Pages: 1 %%Pages: 1 %%Pages: 1 %%Pages: 1 %%Pages: 1 %%Pages: 1 %%Pages: 13 [If I use the cmd line instead of stdin, no problem.]
