Problema com compilação do usando libtool e -shared

[danielgatis]

Pessoal,
estou seguindo o tutorial de compilação do ginga (http://svn.softwarepublico.gov.br/trac/ginga/wiki/Building_Wiki_GingaNCL) e estou com problema na hora de linkar o telemidia-util-cpp. Aparentemente estou tentando compilar uma biblioteca mas sempre me aperece um erro perguntando pelo metodo main. Abaixo segue o erro e o config.log do autogen.sh.

 Erro:

Agradeço desde já e descupem o tamanho do post.

Onde são compilados os arquivos objeto? Aqui só diz que main() não pode ser encontrado.

[danielgatis]

Os objetos já foram compilados quando dei o make anteriormente. Eles se encontram na pasta corrente.

O engraçado é que uma linha acima está imprimido no console

/libtool --tag=CXX   --mode=link g++  -g -O2 -Wl,-soname,libtelemidiautil.so -shared -o libtelemidiautil.so Color.o Thread.o functions.o -lpthread -lpthread

e logo na linha de baixo o shared desaparece:

libtool: link: g++ -g -O2 -Wl,-soname -Wl,libtelemidiautil.so -o libtelemidiautil.so Color.o Thread.o functions.o  -lpthread

alguma dica?

Infelizmente sou meio "cru" com o uso do libtool, mas me parece que a linha de comando está errada.

O que segue --mode=link é a linha de comando do g++:

Código: [Selecionar]

libtool --tag=CXX   --mode=link [color=red]g++  -g -O2 -Wl,-soname,libtelemidiautil.so [color=red]-shared [/color] -o libtelemidiautil.so Color.o Thread.o functions.o -lpthread -lpthread[/color]
-Wl acho que não existe, nunca vi usar virgulas para separar nomes de libs. O uso de -shared está certo, já que você quer gerar um shared object (so). Dessa linha de comando eu não compreendi o "-Wl,-soname,libtelemidiautil.so", o resto parece correto.

Dá uma olhada na documentação do libtool (em http://www.gnu.org/software/libtool/) e do GCC (em http://gcc.gnu.org/).

[danielgatis]

Obrigado! vou ler a documentação.

[ginga_user]

O problema é a versão da libtool, que requer que passe a opcao -Xcompiler antes de -shared para passar isso ao compilador (fonte: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=526547 )

No caso do ginga, basta substituir todas ocorrencias de -shared nos arquivos Makefile.am por -Xcompiler -shared. A seguinte linha faz isso de forma recursiva na árvore:
 

Código: [Selecionar]

find . -name Makefile.am -exec sed -i 's/-shared/-Xcompiler -shared/g' {} \;
