      I’m trying to build current git kc-master on CENTOS 6.8 with toolset…

      • gcc version 6.2.1 20160916 (Red Hat 6.2.1-3) (GCC)
      • GNU ld version 2.27-8.el6

      …and getting the below ld-error:

      Any idea where to put the lever, here?

      ./.libs/libmapi.so: undefined reference to `KC::ECLocale::operator=(KC::ECLocale const&)'

        Hi

        As far as I remember you need libicu-devel to fix this. We should have that to autoconf.

          libicu-devel

          Bo, thanks a lot - worked!

          Additionally I needed:

          • ncurses-devel

          • in common/ECLogger.cpp:
            #include <climits>
            (defines UINT_MAX)

          • in common/ustringutil.cpp l. 1365/1366:
            const_cast <unsigned char>

          assert(wcslen(reinterpret_cast<wchar_t *>(const_cast<unsigned char*>(lpKey1))) == (cbKey1 / sizeof(wchar_t)) - 1);
assert(wcslen(reinterpret_cast<wchar_t *>(const_cast<unsigned char*>(lpKey2))) == (cbKey2 / sizeof(wchar_t)) - 1);

          ++umgfoin.

            Wasn’t aware of the ncurses dependency. Wanted to remove it from my system to test out, but took out several more dependencies.

            The following 4 packages are going to be REMOVED:
    libxml2-devel ncurses-devel php5-devel readline-devel

            We are making libicu a hard requirement now, so in the future this error message you experienced should be gone and instead configure will complain about missing libicu-devel.

            Thanks for reminding me of this problem.

            Bo

                From what I can see this one should come from ncurses. I compiled the master yesterday without problems. When running configure do you see?

                ncurses libs	:	-L/usr/lib64/ncurses6 -lncursesw -ltinfo

                Bo

                  My entry looks different:

                  ncurses libs    :       -lncursesw

                  If I manually add -ltinfo to NCURSES_LIBS = in Makefile, it builds.

                    What does the following commands give you?

                    11:02:47 bo@bo-suse ~/src/kopanocore (master) > ncursesw5-config --libs
-lncursesw -ltinfo
11:02:50 bo@bo-suse ~/src/kopanocore (master) > ncursesw6-config --libs
-L/usr/lib64/ncurses6 -lncursesw -ltinfo

                    Assume not the same as mine?

                    Bo

                      Yes, just -lncursesw

                      [tadao@ando kopanocore]# ncursesw5-config --libs
-lncursesw
[tadao@ando kopanocore]# ncursesw6-config --libs
-bash: ncursesw6-config: Kommando nicht gefunden.

                      “Kommando nicht gefunden” ~ command not found ;-)

                        Yeah that’s the problem. But it used to work?

                          Yes, used to work 2 days ago.

                          My findings:
                          libncurses links against libltinfo. If we don’t/ can’t explicitely specify this dependancy, newer toolchains can be called with ld-flag --copy-dt-needed-entries. As stated here, implicitely satisfying deep-link dependencies is no longer default behaviour for ld. The above flag forces this behaviour.

                          With option LDFLAGS = -Xlinker --copy-dt-needed-entries in Makefile, the dependency is correctly resolved, again.
                          Atleast valid for gcc version 6.2.1 20160916 (Red Hat 6.2.1-3) (GCC)

                            I looked for commits related to configure.ac, but couldn’t find anything that changed that. Did you get any updates from your distribution?

                                That’s wierd, I will create a JIRA ticket to investigate.

                                    Hi @mkromer ,
                                    thanks - read that, too, but though differently stated in the rel-notes of ncurses-5.7-4.20090207.el6, we still get:

                                    [hias@wurzler kopano-core]# ncurses5-config --libs
-lncurses

[hias@wurzler kopano-core]# ncursesw5-config --libs
-lncursesw

[hias@wurzler kopano-core]# pkg-config ncurses --libs
-lncurses

[hias@wurzler kopano-core]# ncurses5-config --version
5.7.20090207

                                    A working fix is switching to ncurses-header instead of curses.h in configure.ac:

                                    AC_CHECK_HEADERS([ncurses.h])
                                    versus
                                    AC_CHECK_HEADERS([curses.h])

                                    ++umgfoin.
