<p class="MsoNormal"><span lang="EN-US">I believe the offending option is `--with-pmix`, since that defaults to `--with-pmix=yes`. You are supposed to pass in the path to pmix installation, e.g. `--with-pmix=/usr/local`.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">Hello MPICH_Developers,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I am having trouble running the configure script on two latest mpich release (3.4a2 and 3.4a3) when I use the flag --with-device=ch4:ucx (no such problems with ch3:sock or ch3:nemesis). It seems that the generated Makefile
often contains two strange compilation and link flags: -Iyes/include and –Lyes/lib.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">To be able to compile the library I had to use the following command to remove those strange flags:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> find . -name Makefile -exec sed -i -e 's/-Iyes\/include\>//g' -e 's/-Lyes\/lib\>//g' {} \;<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">After this step I am able to compile and the resulting library seems ok and appears to performs well (not extensive testing).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">For your information I call the configure script like this:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> ./configure --with-device=ch4:ucx --with-hcoll=/opt/mellanox/hcoll --with-pmix --prefix=/home/publique/depot/mpi/mpich-ch4_ucx-3.4a3 --enable-fast=all --enable-romio --with-file-system=ufs+nfs --enable-shared --enable-sharedlibs=gcc<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I had experienced this problem on the following three configurations:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> mpich-3.4a2 CentOS 7.6 MOFED 4.7<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> mpich-3.4a3 CentOS 7.6 MOFED 4.7<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> mpich-3.4a3 CentOS 7.8 MOFED 4.9<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The architecture is x86_64.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Could someone take a look at this problem ?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Thanks,<o:p></o:p></span></p>
