I tried to compile aeskulap on Centos 7.6 by using the commands ./configure followed by make which resulted in the following errors :
Attempting to build this way is next to pointless and will likely show you errors completely unrelated to why the package won't properly build.
make[4]: *** [dimoimg.o] Error 1 make[4]: Leaving directory `/root/rpmbuild/SOURCES/aeskulap-0.2.2- beta1/dcmtk/dcmimgle/libsrc' make[3]: *** [libsrc-all] Error 2 make[3]: Leaving directory `/root/rpmbuild/SOURCES/aeskulap-0.2.2-beta1/dcmtk/dcmimgle' make[2]: *** [dcmimgle-libsrc-all] Error 2 make[2]: Leaving directory `/root/rpmbuild/SOURCES/aeskulap-0.2.2-beta1/dcmtk' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/root/rpmbuild/SOURCES/aeskulap-0.2.2-beta1' make: *** [all] Error 2
...and even if you were building it correctly you completely skipped the actual errors here. What you've shown can't be used in any significant way to help.
I downloaded the source files from :
http://li.nux.ro/download/nux/dextop/el7/SRPMS/aeskulap-0.2.2-0.17beta1.el7....
As you've already stated and shown here this is a package from a 3rd-party repo, and as such is not supported by the CentOS project. If Nux can't help you then I suggest you look for the package elsewhere or try to (properly) build it yourself. Unfortunately neither of these options is supported here.
