This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "GiNaC -- a C++ library for symbolic computations". The branch, master has been updated via e5eeee53d814cedc12cd725e76b0eb87859cdd77 (commit) from 05b3a16973aad40a9c17ee0f0bd06b02ac4706ef (commit) Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- commit e5eeee53d814cedc12cd725e76b0eb87859cdd77 Author: Alexei Sheplyakov <Alexei.Sheplyakov@gmail.com> Date: Tue Jul 17 06:32:45 2012 +0300 [bugfix] Always #include <lst.h> before using lst. Fixes build error on MinGW. [temp.expl.spec] says: 6 If a template, a member template or the member of a class template is explicitly specialized then that specialization shall be declared before the first use of that specialization that would cause an implicit instantiation to take place, in every translation unit in which such a use occurs; no diagnostic is required. If the program does not provide a definition for an explicit specialization and either the specialization is used in a way that would cause an implicit instantiation to take place or the member is a virtual member function, the program is ill-formed, no diagnostic required. An implicit instantiation is never generated for an explicit specialization that is declared but not defined. Apparently we are breaking this rule (presumably since the commit 99901bd5c742 `Parser can now read GiNaC lists (lst) defined by braces.'). In particular, parser.cpp does not include lst.h (neither directly nor indirectly) which contains explicit specialization of lst::info(). However, parser.cpp (indirectly) includes both container.h and registar.h, so the GiNaC::lst type is declared (and is complete) before the first usage. Thus lst::info() gets implicitly instantiated (using the general definition provided in container.h) when compiling the parser.cpp file, and libginac fails to link properly due to mutliply defined symbols: libtool: link: ccache i686-w64-mingw32-g++ -shared -nostdlib /usr/lib/gcc/i686-w64-mingw32/4.6/../../../../i686-w64-mingw32/lib/../lib/dllcrt2.o /usr/lib/gcc/i686-w64-mingw32/4.6/crtbegin.o .libs/add.o .libs/archive.o .libs/basic.o .libs/clifford.o .libs/color.o .libs/constant.o .libs/ex.o .libs/excompiler.o .libs/expair.o .libs/expairseq.o .libs/exprseq.o .libs/fail.o .libs/factor.o .libs/fderivative.o .libs/function.o .libs/idx.o .libs/indexed.o .libs/inifcns.o .libs/inifcns_trans.o .libs/inifcns_gamma.o .libs/inifcns_nstdsums.o .libs/integral.o .libs/lst.o .libs/matrix.o .libs/mul.o .libs/ncmul.o .libs/normal.o .libs/numeric.o .libs/operators.o .libs/power.o .libs/registrar.o .libs/relational.o .libs/remember.o .libs/pseries.o .libs/print.o .libs/symbol.o .libs/symmetry.o .libs/tensor.o .libs/utils.o .libs/wildcard.o .libs/parse_binop_rhs.o .libs/parser.o .libs/parse_context.o .libs/default_reader.o .libs/lexer.o .libs/parser_compat.o .libs/mod_gcd.o .libs/cra_garner.o .libs/upoly_io.o .libs/gcd_uvar.o .libs/chinrem_gcd.o .libs/collect_vargs.o .libs/divide_in_z_p.o .libs/mgcd.o .libs/optimal_vars_finder.o .libs/pgcd.o .libs/primpart_content.o -L/home/build/GiNaC.pkg/mk/ginac/../../build-tree/inst/all/opt/i686-w64-mingw32/ginac/lib -lcln -L/usr/lib/gcc/i686-w64-mingw32/4.6 -L/usr/lib/gcc/i686-w64-mingw32/4.6/../../../../i686-w64-mingw32/lib/../lib -L/usr/lib/gcc/i686-w64-mingw32/4.6/../../../../i686-w64-mingw32/lib -lstdc++ -lmingw32 -lgcc_s -lgcc -lmoldname -lmingwex -lmsvcrt -ladvapi32 -lshell32 -luser32 -lkernel32 -lmingw32 -lgcc_s -lgcc -lmoldname -lmingwex -lmsvcrt /usr/lib/gcc/i686-w64-mingw32/4.6/crtend.o -O2 -march=i686 -Wl,--enable-auto-import -Wl,--export-all-symbols -o .libs/libginac-2.dll -Wl,--enable-auto-image-base -Xlinker --out-implib -Xlinker .libs/libginac.dll.a Creating library file: .libs/libginac.dll.a .libs/parser.o: In function `_ZNK5GiNaC9containerISt4listE4infoEj': /home/build/GiNaC.pkg/mk/ginac/../../ginac/ginac/container.h:359: multiple definition of `GiNaC::container<std::list>::info(unsigned int) const' .libs/lst.o:/usr/include/c++/4.6/bits/vector.tcc:390: first defined here collect2: ld returned 1 exit status make[4]: *** [libginac.la] Error 1 make[4]: Leaving directory `/home/build/GiNaC.pkg/build-tree/build/ginac-1.6.2/ginac' make[3]: *** [all] Error 2 Thanks to Robert Durkacz for reporting. ----------------------------------------------------------------------- Summary of changes: ginac/parser/default_reader.cpp | 1 + ginac/parser/parser.cpp | 1 + 2 files changed, 2 insertions(+), 0 deletions(-) hooks/post-receive -- GiNaC -- a C++ library for symbolic computations
