Impossible de créer un interpréteur TCL personnalisé avec TclPro1.4: référence non définie à `__ctype_b '

Question

J'essaye de créer un interpréteur TCL personnalisé avec TclPro selon les instructions au TclPro User's Guide Chapitre 7, mais il échoue avec l'erreur de liaison undefined reference to __ctype_b.

J'ai téléchargé et installé TclPro 1.4 à /opt/ajuba/TclPro1.4/, et est l'interprète personnalisé ici, je veux construire:

// file simple.cpp 
#include <proWrap.h> 
int main(int argc, char** argv) 
{ 
    Pro_WrapTclMain(argc, argv, &Tcl_Init); 
    return 0; 
} 

Il ne fait rien, mais appelle à la norme Pro_WrapTclMainTcl_Init.

Je suis en train de construire simple.cpp avec cette commande:

g++ -DNDEBUG -O3 -fpic -Wall -pedantic -I/opt/ajuba/TclPro1.4/include simple.cpp -static -Wl,-R/opt/ajuba/TclPro1.4/linux-ix86/lib -L/opt/ajuba/TclPro1.4/linux-ix86/lib -lwrapper1.4 -ltcl8.3 -o out 

et est ici le premier message d'erreur que je reçois (vous pouvez trouver le journal complet en bas):

/opt/ajuba/TclPro1.4/linux-ix86/lib/libwrapper1.4.a(envargs.o): In function `envargs': 
envargs.c:(.text+0x1e): undefined reference to `__ctype_b' 

Semble __ctype_b est un symbole que TclPro s'attend à définir à libc.a, mais

nm /usr/lib/libc.a | grep __ctype_b 

donne

00000080 T __ctype_b_loc 

donc il n'y a pas __ctype_b défini à libc.a.

La question est: comment créer un interpréteur TCL personnalisé avec TclPro dans cette situation?

Si __ctype_b doit être défini à libc.a, alors comment puis-je obtenir un libc.a approprié?

Je ne suis pas sûr de ce que les détails de votre plate-forme sont, mais this message semblerait tenir la réponse. Essentiellement, vous ajoutez ce code à simple.cpp et recompiler:

#include <ctype.h> 

extern "C" { 
__const unsigned short int **__wrap___ctype_b (void) { 
    return __ctype_b_loc(); 
} 
} 

Vous devez également apparemment cette option à la ligne de liaison: -Wl,--wrap,__ctype_b

Hope this helps ...
