I tried to update my mira from 3.9.4 to 3.9.5, but failed when make The last few lines were given. I used ./configure ―enable-mirastatic. The configure process is OK. I've tried ./configure only before. During make, it gave me another error. g++ -DPACKAGE_NAME=\"mira\" -DPACKAGE_TARNAME=\"mira\" -DPACKAGE_VERSION=\"3.9.5\" -DPACKAGE_STRING=\"mira\ 3.9.5\" -DPACKAGE_BUGREPORT=\"\" -DPACKAGE_URL=\"\" -DPACKAGE=\"mira\" -DVERSION=\"3.9.5\" -DSTDC_HEADERS=1 -DHAVE_SYS_TYPES_H=1 -DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1 -DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1 -DENABLE64=1 -DHAVE_DLFCN_H=1 -DLT_OBJDIR=\".libs/\" -DYYTEXT_POINTER=1 -DSTDC_HEADERS=1 -DHAVE__BOOL=1 -DHAVE_STDBOOL_H=1 -Drestrict=__restrict -DHAVE_STDLIB_H=1 -DHAVE_MALLOC=1 -DHAVE_STDLIB_H=1 -DHAVE_REALLOC=1 -DHAVE_STRFTIME=1 -DHAVE_FLOOR=1 -DHAVE_MEMSET=1 -DHAVE_POW=1 -DHAVE_SQRT=1 -DHAVE_FSEEKO=1 -DHAVE_ISBLANK=1 -DHAVE_NAMESPACES=/\*\*/ -DHAVE_STD=/\*\*/ -DHAVE_STL=/\*\*/ -DHAVE_BOOST=/\*\*/ -DHAVE_BOOST_THREAD=/\*\*/ -DHAVE_BOOST_REGEX=/\*\*/ -DHAVE_BOOST_SYSTEM=/\*\*/ -DHAVE_BOOST_FILESYSTEM=/\*\*/ -DHAVE_BOOST_IOSTREAMS=/\*\*/ -DDEVELOPMENTVERSION=0 -DBOUNDTRACKFLAG=1 -DBUGTRACKFLAG=1 -I. -I../../src -DPUBLICQUIET -mmacosx-version-min=10.5 -O3 -funroll-loops -pthread -I/opt/local/include -I/usr/include -std=c++0x -Werror=unused-value -MT main.o -MD -MP -MF .deps/main.Tpo -c -o main.o main.C mv -f .deps/main.Tpo .deps/main.Po /bin/sh ../../libtool --tag=CXX --mode=link g++ -DPUBLICQUIET -mmacosx-version-min=10.5 -O3 -funroll-loops -pthread -I/opt/local/include -I/usr/include -std=c++0x -Werror=unused-value -static-libgcc -static-libstdc++ -L/Users/qingdaoalbert/Downloads/mira-3.9.5/OSXstatlibs -L../io/ -L../util/ -L../errorhandling/ -L../mira -L../caf/ -L/opt/local/lib -all-static -L/Users/qingdaoalbert/Downloads/mira-3.9.5/OSXstatlibs -Wl,-search_paths_first -L/Users/qingdaoalbert/Downloads/mira-3.9.5/OSXstatlibs -Wl,-search_paths_first -L/opt/local/lib -lboost_thread-mt -lboost_regex-mt -lboost_system-mt -lboost_filesystem-mt -lboost_iostreams-mt -lz -lbz2 -L/opt/local/lib/gcc47 -L/opt/local/lib -lboost_thread-mt -lboost_regex-mt -lboost_system-mt -lboost_filesystem-mt -lboost_iostreams-mt -lz -lbz2 -o main main.o -lmiraerrorhandling -L/Users/qingdaoalbert/Downloads/mira-3.9.5/OSXstatlibs -Wl,-search_paths_first -L/Users/qingdaoalbert/Downloads/mira-3.9.5/OSXstatlibs -Wl,-search_paths_first -L/opt/local/lib -lboost_thread-mt -lboost_regex-mt -lboost_system-mt -lboost_filesystem-mt -lboost_iostreams-mt -lz -lbz2 -L/opt/local/lib/gcc47 -L/opt/local/lib -lboost_thread-mt -lboost_regex-mt -lboost_system-mt -lboost_filesystem-mt -lboost_iostreams-mt -lz -lbz2 -L/usr/lib -lexpat libtool: link: warning: complete static linking is impossible in this configuration libtool: link: g++ -DPUBLICQUIET -mmacosx-version-min=10.5 -O3 -funroll-loops -pthread -I/opt/local/include -I/usr/include -std=c++0x -Werror=unused-value -static-libgcc -static-libstdc++ -Wl,-search_paths_first -Wl,-search_paths_first -o main main.o -Wl,-search_paths_first -Wl,-search_paths_first -Wl,-bind_at_load -L/Users/qingdaoalbert/Downloads/mira-3.9.5/OSXstatlibs -L../io/ -L../util/ -L../errorhandling/ -L../mira -L../caf/ -L/opt/local/lib -L/opt/local/lib/gcc47 -lmiraerrorhandling -lboost_thread-mt -lboost_regex-mt -lboost_system-mt -lboost_filesystem-mt -lboost_iostreams-mt -lz -lbz2 -L/usr/lib /opt/local/lib/libexpat.a -pthread ld: file not found: libstdc++.a collect2: error: ld returned 1 exit status make[3]: *** [main] Error 1 make[2]: *** [all-recursive] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 qingdaoalberttekiMac-Pro:mira-3.9
