Title: /crt1.o(.text+0x2c): undefined reference to `main\'
Post by: cmisip on May 30, 2004, 04:33:49 pm

I am trying to compile xu4.  I get this error using gcc 2.95.3

/usr/local/bin/arm-linux-gcc -DHAVE_BACKTRACE=1 -DHAVE_VARIADIC_MACROS=1 -Wall -I. -I/home/cmisip/develop/usr/local/include -I/home/cmisip/develop/usr/local/include/SDL -DQWS -D_REENTRANT -Dmain=SDL_main -I/home/cmisip/develop/usr/local/include/libxml2 -DICON_FILE=\"/usr/local/share/pixmaps/u4.bmp\" -DVERSION=\"0.9\" -ggdb -rdynamic -o dumpsavegame util/dumpsavegame.o savegame.o io.o names.o
/usr/local/arm-linux/lib/crt1.o: In function `_start\':
/usr/local/arm-linux/lib/crt1.o(.text+0x2c): undefined reference to `main\'
collect2: ld returned 1 exit status
make: *** [dumpsavegame] Error 1


Anybody care to comment what is going on?

Thanks.

Seems to be a SDL application. I recommend -lSDLmain

I added -ISDLmain but get the same error.

Does it help to say that xu4 was not meant to be compiled with gcc 2.95.x because of anonymous union structs (I changed those).   The source files  in u4/util compile fine on gcc 3.2.2.  What changes does the makefile need?

Thanks again

You did -ISDLmain while I recommended -lSDLmain

Oh please elaborate.  They look the same to me?  And where do I put it?  
Thanks.

Uhm... it\'s two different letters. One is a uppercase I, as in Isadora, the other is a lowercase l as in library
(The point where you placed it was ok)

On a positive note, compilation proceeds up to this point and creates a u4 binary drop in replacement to xu4 from http://inter.zon.free.fr/zaurus_index.htmlwhich (http://inter.zon.free.fr/zaurus_index.htmlwhich) runs on the zaurus 5600.  

Dont know the long term consequences of this though.  It runs and I am able to move, kill monsters and save the game.

I still would like to know where I am wrong.
