Hi again, As a followup - I ran this command (do I need to set LD_LIBRARY_PATH?) [pol@polhost /]$ sudo find . -name "icu*" | grep -v Downloads | more And got: ./usr/local/sbin/icupkg ./usr/local/bin/icuinfo ./usr/local/bin/icu-config ./usr/local/lib/icu ./usr/local/lib/pkgconfig/icu-io.pc ./usr/local/lib/pkgconfig/icu-uc.pc ./usr/local/lib/pkgconfig/icu-i18n.pc ./usr/local/share/icu ./usr/local/share/man/man8/icupkg.8 ./usr/local/share/man/man1/icu-config.1 ./usr/local/include/unicode/icuplug.h ./usr/local/include/unicode/icudataver.h ./usr/bin/icuinfo ./usr/bin/icu-config-64 ./usr/bin/icu-config ./usr/lib64/icu ./usr/lib64/pkgconfig/icu-io.pc ./usr/lib64/pkgconfig/icu-uc.pc ./usr/lib64/pkgconfig/icu-i18n.pc ./usr/lib/jvm/java-10-openjdk-10.0.1.10-3.fc28.x86_64/legal/java.base/icu.md ./usr/share/maven-metadata/icu4j.xml ./usr/share/icu ./usr/share/licenses/icu4j ./usr/share/jython/javalib/icu4j_icu4j.jar ./usr/share/maven-poms/icu4j ./usr/share/maven-poms/icu4j/icu4j.pom ./usr/share/java/icu4j ./usr/share/java/icu4j/icu4j.jar ./usr/share/doc/icu4j ./usr/share/man/man1/icu-config.1.gz ./usr/share/man/man1/icuinfo.1.gz ./usr/include/boost/regex/icu.hpp ./usr/include/unicode/icuplug.h ./usr/include/unicode/icudataver.h [pol@polhost /]$ It seems that the library was installed, but the PostgreSQL make command can't "see" the libs?
