DESCRIPTION="Based on the ${ECLASS} eclass" |

|
| 17 |
# This function generate linker scripts in /usr/lib for dynamic |
| 18 |
# libs in /lib. This is to fix linking problems when you have |
| 19 |
# the .so in /lib, and the .a in /usr/lib. What happens is that |
| 20 |
# in some cases when linking dynamic, the .a in /usr/lib is used |
| 21 |
# instead of the .so in /lib due to gcc/libtool tweaking ld's |
| 22 |
# library search path. This cause many builds to fail. |
| 23 |
# See bug #4411 for more info. |
| 24 |
# |
| 25 |
# To use, simply call: |
| 26 |
# |
| 27 |
# gen_usr_ldscript libfoo.so |
| 28 |
# |
| 29 |
# Note that you should in general use the unversioned name of |
| 30 |
# the library, as ldconfig should usually update it correctly |
| 31 |
# to point to the latest version of the library present. |

Because Gentoo have critical dynamic libraries |

in /lib, and the static versions in /usr/lib, we |
| 44 |
need to have a "fake" dynamic lib in /usr/lib, |
| 45 |
otherwise we run into linking problems. |

# This function is for bulk patching, or in theory for just one |
| 65 |
# or two patches. |
| 66 |
# |
| 67 |
# It should work with .bz2, .gz, .zip and plain text patches. |
| 68 |
# Currently all patches should be the same format. |
| 69 |
# |
| 70 |
# You do not have to specify '-p' option to patch, as it will |
| 71 |
# try with -p0 to -p5 until it succeed, or fail at -p5. |
| 72 |
# |
| 73 |
# Above EPATCH_* variables can be used to control various defaults, |
| 74 |
# bug they should be left as is to ensure an ebuild can rely on |
| 75 |
# them for. |
| 76 |
# |
| 77 |
# Patch/Patches should preferibly have the form of: |
| 78 |
# |
| 79 |
# ??_${ARCH}_foo.${EPATCH_SUFFIX} |
| 80 |
# |
| 81 |
# For example: |
| 82 |
# |
| 83 |
# 01_all_misc-fix.patch.bz2 |
| 84 |
# 02_sparc_another-fix.patch.bz2 |
| 85 |
# |
| 86 |
# This ensures that there are a set order, and you can have ARCH |
| 87 |
# specific patches. |
