i need to compile a self contained httpd distribution, which need stricts library search paths in the binaries. i found out that something is messing up the resulting binaries. i use the following build settings: export OBJECT_MODE=64 export AR="/usr/bin/ar -X64" export LD="/usr/bin/ld" export RM="/usr/bin/rm -f" export CC="/usr/bin/gcc" export CXX="/usr/bin/g++" export LTFLAGS="--tag=CC --silent" export CFLAGS="-maix64 -fsigned-char -D_LARGE_FILES -O2 -I$OPENSSLSPATH/include -I/opt/freeware/include" export LDFLAGS="-L$APPATH/lib -L$OPENSSLPATH/lib -L/opt/freeware/lib64 -L/opt/freeware/lib -Wl,-blibpath:$APPATH/lib:/usr/lib:/lib" export CXXFLAGS=$CFLAGS the resulting bins contains a messed up search path (httpd for example): root@aixbuildhostng: /tmp/apatest/bin # dump -X64 -ovH httpd httpd: ***Object Module Header*** # Sections Symbol Ptr # Symbols Opt Hdr Len Flags 4 0x00000000 0 120 0x100f Flags=( RELFLG EXEC LNNO LSYMS DYNLOAD DEP_SYSTEM ) Timestamp = "Jun 24 12:17:59 2020" Magic = 0x1f7 (64-bit XCOFF) ***Optional Header*** Tsize Dsize Bsize Tstart Dstart 0x00077ad4 0x0000c59c 0x00003898 0x10000240 0x20000d14 SNloader SNentry SNtext SNtoc SNdata 0x0004 0x0002 0x0001 0x0002 0x0002 TXTalign DATAalign TOC vstamp entry 0x0007 0x0004 0x2000bcc8 0x0001 0x200061a0 maxSTACK maxDATA SNbss magic modtype 0x00000000 0x00000000 0x0003 0x010b 1L ***Loader Section*** Loader Header Information VERSION# #SYMtableENT #RELOCent LENidSTR 0x00000001 0x000006c1 0x000012ee 0x000000c3 #IMPfilID OFFidSTR LENstrTBL OFFstrTBL 0x00000007 0x0001d130 0x00009267 0x0001d1f3 ***Import File Strings*** INDEX PATH BASE MEMBER 0 /opt/freeware/lib:/tmp/apatest/lib:/tmp/apatest/lib:/usr/lib:/lib 1 libpcre.a libpcre.so.1 2 libaprutil-1.so 3 libexpat.a libexpat.so.1 4 libapr-1.so 5 libpthread.a shr_xpg5_64.o 6 libc.a shr_64.o Index0 should contain only "/tmp/apatest/lib:/usr/lib:/lib" IMHO. i highly supsect some auttool/libtool rubbish acting up somewhere somehow. funnily this only concern the binaries (httpd,ab...), the modules are all correctly linked. any hints whats going on, i'm out of ideas? i tried to relink with rtl_enable but this kills the binary... rtl_enable -X64 -o /tmp/aptest/bin/httpd_fixed /tmp/aptest/bin/httpd -blibpath:/tmp/aptest/lib:/usr/lib:/lib root@aixbuildhostng: /home/packagebuilder/apache2-itsv # dump -X64 -ovH /tmp/aptest/bin/httpd_fixed /tmp/aptest/bin/httpd_fixed: ***Object Module Header*** # Sections Symbol Ptr # Symbols Opt Hdr Len Flags 4 0x00000000 0 120 0x100f Flags=( RELFLG EXEC LNNO LSYMS DYNLOAD DEP_SYSTEM ) Timestamp = "Jun 24 14:53:19 2020" Magic = 0x1f7 (64-bit XCOFF) ***Optional Header*** Tsize Dsize Bsize Tstart Dstart 0x0007f098 0x0000dc68 0x00003890 0x00000000 0x00000000 SNloader SNentry SNtext SNtoc SNdata 0x0004 0x0002 0x0001 0x0002 0x0002 TXTalign DATAalign TOC vstamp entry 0x0007 0x0004 0x0000afb8 0x0001 0x00005490 maxSTACK maxDATA SNbss magic modtype 0x00000000 0x00000000 0x0003 0x010b 1L ***Loader Section*** Loader Header Information VERSION# #SYMtableENT #RELOCent LENidSTR 0x00000001 0x000006c1 0x000015c6 0x0000009f #IMPfilID OFFidSTR LENstrTBL OFFstrTBL 0x00000007 0x0001feb0 0x00009267 0x0001ff4f ***Import File Strings*** INDEX PATH BASE MEMBER 0 /tmp/aptest/lib:/usr/lib:/lib 1 libc.a shr_64.o 2 libpthread.a shr_xpg5_64.o 3 libapr-1.so 4 libpcre.a libpcre.so.1 5 libaprutil-1.so 6 libexpat.a libexpat.so.1 root@aixbuildhostng: /home/packagebuilder/apache2-itsv # /tmp/aptest/bin/httpd_fixed -t -D DUMP_MODULES Illegal instruction​
