<br>
the --with-lapack flag is meant to specify the flags necessary to link <br>
against a (Blas+)Lapack library, not to specify a directory where Lapack <br>
source files can be found.<br>
Renaming a source file will also not change the name of the functions <br>
defined in the source.<br>
<br>
Also a lot has changed between Ipopt 3.11 and the 3.13 source that you <br>
seem to use. Thus, looking at the documentation for current Ipopt <br>
(<a href="https://coin-or.github.io/Ipopt/" rel="noreferrer" target="_blank">https://coin-or.github.io/Ipopt/</a>) might be less confusing. For example, <br>
regarding Lapack, the easiest should be to use your systems package <br>
manager to install Lapack <br>
(<a href="https://coin-or.github.io/Ipopt/INSTALL.html#SYSTEMPACKAGES_MSYS" rel="noreferrer" target="_blank">https://coin-or.github.io/Ipopt/INSTALL.html#SYSTEMPACKAGES_MSYS</a>), <br>
which Ipopts configure would then hopefully be able to pick up <br>
automatically.<br>
