Autoconf build fails if libcurl isn't installed, --disable-byterange is ignored

[WardF]

As a followup to esupport question RZG-350418.

When libcurl isn't present on a system, configure errors out with

checking whether byte range support is enabled... no
configure: error: curl required for byte range support. Install curl or build without --enable-byterange.

This occurs even if --disable-byterange is passed to ./configure.

[DennisHeimbigner]

Code in configure.ac is this:

if test "x$found_curl" = xno ; then
  AC_MSG_ERROR([curl required for byte range support. Install curl or build without --enable-byterange.])
  enable_byterange=no
fi 

Instead, it needs to looks somthing like this:

if test "x$found_curl" = xno  && test "x$enable_byterange" = xyes ; then
  AC_MSG_ERROR([curl required for byte range support. Install curl or build without --enable-byterange.])
  enable_byterange=no
fi

Hi. I face the same problem, Have you find any solution?

Supposedly this was fixed by PR https://github.com/Unidata/netcdf-c/pull/1392.

Hello, I am trying to compile maob with netcdf (https://sigma.mcs.anl.gov/moab/building-moab/) and I am getting an error in respect to this issue (see end of message). eventhought this was supposed to be fixed already, for moab I have used ./configure --enable-rel --download-netcdf=https://github.com/Unidata/netcdf-c/archive/refs/tags/v4.9.2.tar.gz which should download the last version any idea/help to solve this?

@otaolafranc I'm unfamiliar with moab, but it appears that DAP is enabled, and thus byte-range is enabled, but the dependency libcurl is not installed. You'll need to modify the configure command being issued to netCDF-C so that DAP is disabled altogether, or perhaps just pass --disable-byterange.

[WardF]

You could also install libcurl-dev, or whatever the appropriate package for your platform is, to provide the development headers and library for libcurl.

looks like sudo aptitude install libcurl4-openssl-dev did the job (at least it looks like. thanks!)
