209 |

210 |

# 2) In general, libtool expects an argument such as `--tag=CXX' when
|
213 |
|
|
# using the C++ compiler, because that will enable the settings
|
214 |
|
|
# detected when C++ support was being configured. However, when no
|
215 |
|
|
# such flag is given in the command line, libtool attempts to figure
|
216 |
|
|
# it out by matching the compiler name in each configuration section
|
217 |
|
|
# against a prefix of the command line. The problem is that, if the
|
218 |
|
|
# compiler name and its initial flags stored in the libtool
|
219 |
|
|
# configuration file don't match those in the command line, libtool
|
220 |
|
|
# can't decide which configuration to use, and it gives up. The
|
221 |
|
|
# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
|
222 |
|
|
# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to

# course is problematic at this point. So, we get the top-level
