 |
|
Hi, I'm trying to generate an ebuild for mldonkey-3.1.3 from the 3.1.0 version.
When compiling, I get the following error and I don't know what it could be:
| Code: |
undefined reference to symbol 'png_access_version_number@@PNG15_0'
|
Can anybody give me a clue about what direction to follow?
Regards. |

I found out that there is a missing dependency with "png15" and that I should add "-lpng15" to LDFLAGS before configuring.
I've tried with "append-ldflags -lpng15" at the end of the setup section but that doesn't seem to work. |

| Passing libraries through $LDFLAGS is wrong and not guaranteed to work. Indeed, if the upstream build system is correctly written, it is very likely to fail. Assuming the upstream build system follows standard practices, you can pass the library via $LDLIBS or possibly $LIBS. |

You're right, I finally did it that way and changed the following fuction in the ebuild:
| Code: |
src_configure() {
# the dirs are not (yet) used, but it doesn't hurt to specify them anyway
# onlygui Disable all nets support, build only chosen GUI
if use gtk || use guionly; then
myconf="--enable-gui=newgui2"
else
myconf="--disable-gui"
fi
if use guionly; then
myconf="${myconf} --disable-multinet --disable-donkey"
fi
cd "${S}"
local my_extra_libs
if use gd; then
my_extra_libs="-lpng15"
fi
econf LIBS="${my_extra_libs}"\
--sysconfdir=/etc/mldonkey \
--sharedstatedir=/var/mldonkey \
--localstatedir=/var/mldonkey \
--enable-checks \
--disable-batch \
$(use_enable bittorrent) \
$(use_enable fasttrack) \
$(use_enable gnutella) \
$(use_enable gnutella gnutella2) \
$(use_enable gd) \
$(use_enable magic) \
${myconf}
}
