Installation broke..
Recently I tried to compile a (c++) package which then borked at me that libstdc++-devel was not installed. After fishing the application that failed from the config.log I distilled that the following c++ application does not compile for me: #include using namespace std; int main () { string astring="Hello World"; astring.remove(0, 6); return 0; } I removed any and all gcc, g++, and libstd stuff from my machine and did new apt-get's for g++ gcc etc. (all from testing) So I now have a pretty default gcc 3.3.1 installation, INCLUDING libstdc++5-3.3-dev (3.3.1-0pre0), but I still cant compile the above simple application. [EMAIL PROTECTED]:arts$g++ test.cpp test.cpp: In function `int main()': test.cpp:6: error: `remove' undeclared (first use this function) test.cpp:6: error: (Each undeclared identifier is reported only once for each function it appears in.) Is this a known problem? Do you have any suggestions to further investigate? Any help is appreciated.. Please cc answers; as I am not subscribed to the list. -- Thomas Zander
Bug#208981: gcc-3.3: typeof(nonconst+const) is const
Package: gcc-3.3 Version: 1:3.3.2-0pre1 Severity: minor Try compiling the following function with "gcc-3.3 -c const.c". GCC gives "assignment of read-only variable" warnings on the indicated lines. This shows that __typeof__ treats the corresponding arguments as const. void fn(void) { int n; const int c; { __typeof__(n) a1; a1=0; } { __typeof__(c) a2; a2=0; } /* warning */ { __typeof__(n+n) b0; b0=0; } { __typeof__(n+c) b1; b1=0; } /* warning */ { __typeof__(c+n) b2; b2=0; } { __typeof__(c+c) b3; b3=0; } /* warning */ { __typeof__(1+n) c0; c0=0; } { __typeof__(1+c) c1; c1=0; } /* warning */ { __typeof__(n+1) c2; c2=0; } { __typeof__(c+1) c3; c3=0; } { __typeof__(((int)n)+((int)n)) d0; d0=0; } { __typeof__(((int)n)+((int)c)) d1; d1=0; } /* warning */ { __typeof__(((int)c)+((int)n)) d2; d2=0; } { __typeof__(((int)c)+((int)c)) d3; d3=0; } /* warning */ { __typeof__(((const int)n)+((const int)n)) e0; e0=0; } { __typeof__(((const int)n)+((const int)c)) e1; e1=0; } /* warning */ { __typeof__(((const int)c)+((const int)n)) e2; e2=0; } { __typeof__(((const int)c)+((const int)c)) e3; e3=0; } /* warning */ } The behavior at b1 and b2 seems inconsistent. If n+c is const, then surely c+n should be as well, given that the addition operator is commutative in all other respects. Cases c0 to c3 show that GCC treats an integer constant as a non-const rvalue. Cases d0 to d3 and e0 to e3 show that casts have no effect on the constness of the result; that can't be right either. I think it would be cleanest to make the addition operator always return a non-const rvalue, regardless of whether the operands are const. After all, the result is supposed to be freshly computed. -- System Information: Debian Release: testing/unstable Architecture: i386 Kernel: Linux Astalo 2.4.21-kon.astalo.1 #1 la elokuun 23. 01:05:31 EEST 2003 i686 Locale: [EMAIL PROTECTED], [EMAIL PROTECTED] Versions of packages gcc-3.3 depends on: ii binutils 2.14.90.0.4-0.1 The GNU assembler, linker and bina ii cpp-3.3 1:3.3.2-0pre1 The GNU C preprocessor ii gcc-3.3-base 1:3.3.2-0pre1 The GNU Compiler Collection (base ii libc62.3.2-2 GNU C Library: Shared libraries an ii libgcc1 1:3.3.2-0pre1 GCC support library -- no debconf information
