Hello, In a tcsh shell, with
setenv QT4DIR /usr/local/qt-4.1.4 ./configure --with-frontend=qt4 --with-version-suffix=1.5.0alpha1 I get the message checking size of wchar_t... configure: error: cannot compute sizeof (wchar_t), 77 See `config.log' for more details. The log says: configure:6941: checking size of wchar_t configure:7260: g++ -o conftest -g -O2 -W -Wall conftest.cc -lc -lm >&5 configure:7263: $? = 0 configure:7265: ./conftest ld.so.1: conftest: fatal: libstdc++.so.5: open failed: No such file or directory libstdc++.so.5 is not found (it is all right in /usr/local/lib) so I ran ./configure LDFLAGS=-R/usr/local/lib --with-frontend=qt4 --with-version-suffix=1.5.0alpha1 to ask for inclusion of /usr/local/lib path in the executables. Configure runs OK, but now lyx fails at the very end of compilation with: ld: warning: file /usr/local/lib/libiconv.so: attempted multiple inclusion of file ld: warning: file /usr/local/lib/libstdc++.so: linked to /usr/local/lib/./libstdc++.so: attempted multiple inclusion of file I've compiled every release of lyx on Solaris, I've never had to ask explicitly for a PATH to libraries (but -lnsl and -lsocket when these were missing), and I get it all right, e.g. for 1.4.3: -> dump -Lv /usr/local/bin/lyx-1.4.3-qt /usr/local/bin/lyx-1.4.3-qt: **** DYNAMIC SECTION INFORMATION **** .dynamic: [INDEX] Tag Value [1] NEEDED libintl.so.3 [...] [22] RUNPATH /usr/local/qt-3.3.4/lib:/usr/local/lib/.:/usr/local/lib:/usr/local/lib: /usr/openwin/lib [23] RPATH /usr/local/qt-3.3.4/lib:/usr/local/lib/.:/usr/local/lib:/usr/local/lib: /usr/openwin/lib Any clue ? -- Jean-Pierre
