Dear all: Below are my source code. #include<stdio.h> #include<asm-i386/Types.h> int main(void){ u64 u64value; u64value = 0x2e32; printf("u64value = %0x\n",u64value); } While compiling it, the gcc tells me that it cannot find the Type.h. I also type gcc -v and get message as below [root@localhost ~]# gcc -v Using built-in specs. Target: i386-redhat-linux Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-libgcj-multifile --enable-languages=c,c++,objc,obj-c++,java,fortran,ada --enable-java-awt=gtk --disable-dssi --with-java-home=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre --with-cpu=generic --host=i386-redhat-linux Thread model: posix gcc version 4.1.1 20060525 (Red Hat 4.1.1-1) I have read the gcc official document but it seems doesn't mention where to set or get the standard include path. Would someone please tell me where can I find the document which will clarify my concern?
