Here is 'minimal.mp': input TEX beginfig(1) draw thelabel.top(TEX("90"), origin); endfig; end It runs fine through mpost, but running 'mptopdf minimal.mp' instead produces: MPtoPDF 1.3.3 : running 'texexec --mptex minimal.mp' TeXExec | processing graphic 'minimal.mp' This is MetaPost, Version 0.993 (Web2C 7.5.6) (/usr/share/texmf/web2c/natural.tcx) (minimal.mp (/usr/share/texmf-texlive/metapost/base/TEX.mp) (mptextmp.mp

MPtoPDF 1.3.3 : no filename matches minimal (After running mpost, the mptopdf command works fine, so delete all files except minimal.mp, then run 'mptopdf minimal.mp' to see the problem.) I'm using the Debian unstable texlive/context packages on i386 (using mkii). Do others see this problem? I don't think it's related to the mpost version or to the Debian packaging. I just tried a moderately recent 'minimals' and mpost 1.110, and the problem is the same. -Sanjoy
