poppler merges fine under uClibc. Perhaps it's related to the use of uClibc++ vs uClibc alone. uClibc ~ # qfile libm.so -v sys-libs/uclibc-0.9.28-r2 (/usr/lib/libm.so) uClibc ~ # qlist -Uve poppler app-text/poppler-0.5.4 (zlib)
can you try: CXX=g++-uc emerge poppler
<psm> that is a usual failure with uClibc++, nothing specific to this package <psm> libstdc++ is linked against libm.so, but libuClibc++.so not, there are many packages that need -lm <psm> it is rather laziness of app's developer not adding explicitely -lm, if he uses libm functions <psm> this bug should be probably converted into some generic uClibc++/libm tracker <psm> live,evas,kaffe,dbh,tcc,faac,libmp4v2,musicbrainz are others
poppler needs fixing to link against libm
Sorry, I do not have uclibc at the moment. Feel free to apply a patch if you got one :)
Created attachment 133517 [details, diff] poppler-0.5.4-libm.patch Correct way to handle libm. I haven't managed to get eautoreconf to work, even if it works fine to just run auroreconf in $S.
fwiw. problem seems to be solved in poppler-0.6.1
This is reported to be fixed with newer poppler and poppler-0.5.4 is no longer in tree, closing.
