MEXNC and OPeNDAP: What Doesn't Work

Linux x86 RedHat 7.3, Libdap 3.6.2, Libnc-dap 3.6.0

Baseline system

• kernel-2.4.20-18.7
• curl-7.9.5-2
• libxml2-2.4.19-4
• openssl-0.9.6b-35.7
• gcc-2.96-113

1. The existing RPM version of curl is too old, so version 7.15.3 is configured with

   ./configure --prefix=/home/jevans/opendap --disable-shared
   

2. The existing RPM version of libxml2 is too old, so version 2.6.24 is configure with

   ./configure --prefix=/home/jevans/opendap --disable-shared
   

   but it will not compile, giving us the error message

   mlIO.c: In function `xmlCheckFilename':
   xmlIO.c:619: parse error before `struct'
   xmlIO.c:621: `stat_buffer' undeclared (first use in this function)
   xmlIO.c:621: (Each undeclared identifier is reported only once
   xmlIO.c:621: for each function it appears in.)
   /usr/include/sys/stat.h:345: warning: inlining failed in call to `stat'
   xmlIO.c:621: warning: called from here

   make[1]: *** [all-recursive] Error 1
   make[1]: Leaving directory `/home/jevans/src/libxml2-2.6.24'
   make: *** [all] Error 2
   

   This may mean that this machine is just too old. Since I'll get hauled off to jail if I'm caught on this machine, no further heroics will be attempted.
