With dev-libs/jsoncpp present in the system it works. Found JsonCpp: /usr/lib64/libjsoncpp.so Dev-libs/jsoncpp is missing as dependency in .ebuild.
(In reply to David Kredba from comment #9) > With dev-libs/jsoncpp present in the system it works. > Found JsonCpp: /usr/lib64/libjsoncpp.so > > Dev-libs/jsoncpp is missing as dependency in .ebuild. JsonCpp is not a hard dependency. This is primarily a configuration problem; my ebuild builds fine without dev-libs/jsoncpp when USE="-examples". Please see https://bugs.gentoo.org/show_bug.cgi?id=533606#c5.
The reason for the difference between my ebuild (which configures without dev-libs/jsoncpp) and the current one in tree is the following: 126c145,147 < for x in expat freetype gl2ps hdf5 jpeg libxml2 netcdf oggtheora png tiff zlib; do --- > # missing: VPIC alglib exodusII freerange ftgl libproj4 mrmpi sqlite utf8 verdict xmdf2 xmdf3 > for x in expat freetype gl2ps hdf5 jpeg jsoncpp libxml2 netcdf oggtheora png tiff zlib; do > ebegin "Dropping bundled ${x}" 127a149 > eend $? The bundled jsoncpp is not dropped in my ebuild, which suggests that jsoncpp is a hard dependency, after all.
Removing jsoncpp from these lines for x in expat freetype gl2ps hdf5 jpeg jsoncpp libxml2 netcdf oggtheora png tiff zlib; do ebegin "Dropping bundled ${x}" rm -r ThirdParty/${x}/vtk${x} || die eend $? did not, as expected, result in configuration succeeding. I get the same error. Patch vtk-6.1.0-system.patch is the reason. If that is omitted, then configuration succeeds. Whatever the case, it seems that jsoncpp is a required dependency (at least it is if we want to avoid using bundled third party libraries!) After adding it to RDEPEND, there is no more jsoncpp error. I will post my revised ebuild. However, with USE="examples" configuration is still failing, so that problem remains unresolved. I am also skeptical about all the patches, they look like they were taken over from the 6.0.0 ebuild. Are they necessary? I can get vtk-6.1.0 to build without them.
Created attachment 392606 [details] New ebuild with jsoncpp as required dependency This version pulls jsoncpp.

That is good news; strangely, it fails for me at installation (bug 534036). Do you have USE="web", perhaps?
