Description:
When compiling the release I run into the following error:

  g++ -DUNDEF_THREADS_HACK -I. -I. -I.. -I./../include  -I../include -I./.. -I..
  -I..      -O3 -DDBUG_OFF   -fno-implicit-templates -fno-exceptions -fno-rtti -
c -o sql_string.o `test -f sql_string.cc || echo './'`sql_string.cc
sql_string.cc: In method `bool String::set (double, unsigned int)':
sql_string.cc:180: implicit declaration of function `int snprintf (...)'
make: 1254-004 The error code from the last command is 1.

Please help.

How to repeat:
make

Configured it with:

CC="gcc -pipe -mcpu=power -Wa,-many"
CFLAGS="-felide-contructors -fno-exceptions -fno-rtti"
CXX="gcc -pipe -mcpu=power -Wa,-many"
CXXFLAGS="-felide-contructors -fno-exceptions -fno-rtti"

./configure --prefix=/usr/local --with-low-memory

I have verified this one a clients AIX5.2 Machine

When compiling with GCC 3.3.2 I get the same errors as reported in Bug-report 1676 (when compiling MySQL 4.0.16).

Sorry but we can't repeat this as we don't have access to an AIX 5.2 box to debug this.  MySQL 4.0.17 compiles perfectly on the AIX 5.1 box we can access.

The compiler failure is quite strange as configure.in checks if snprintf() exists and defines HAVE_SNPRINTF in this case

The code that gives an error is:

ifdef HAVE_SNPRINTF
  buff[sizeof(buff)-1]=0;                       // Safety
  snprintf(buff,sizeof(buff)-1, "%.*f",(int) decimals,num);
#else
...

The question is "Why is snprintf() not defined in the system include file (should be stdio.h, included from my_global.h)".

The reason I can come up with are:
- snprintf() is somehow missing from the include files.
- Some compiler bug
- Some bug in the include files
- The compiler needs some special option to enable snprintf

One way to find out is to take the compile line but replace "-o sql_string.o" with -E -o sql_string.cpp and attach the .ccp file to this bug report.

Monty

I can't access my AIX 5.2 right now. I will try it sometime next week and
let you know the results.

I don't have the snprintf error anymore. I've now configured it with:

CFLAGS="-O2 -mcpu=powerpc -Wa,-many"
CXX=gcc
CXXFLAGS="-O2 -mcpu=powerpc -Wa,-many -felide-constructors -fno-exceptions -fno-
rtti"
./configure --prefix=/usr/local/mysql --with-extra-charsets=complex --with-serve
r-suffix="-pro" --enable-threads-safe-client --enable-local-infile --with-named-
z-libs=no --disable-shared

This results in the same curses errors as report in bugreport 1676 for MySQL 4.0.16.
