最新版的 dpkg 吐了下面這一大堆 warning messages。
很多是我本來就知道的,不過眼不見為淨…
現在既然有詳細 message 列表,就順便問一下…
怎樣把這些用不到的 linked lib 拿掉?
以 gcin-gb-toggle 為例,根本只用到 gdk 沒用到 gtk,去掉多餘 link 檔案可以大幅縮減。

這個我也有點好奇,用 pkg-config 的本來就會這樣?
分開寫?不要通通都直接用 gtk+-2.0?

gcin-setup-tab shouldn't be linked with libpango |
GTK 不是都用 pango 去 draw string,怎麼可能沒有用到。

ps.我現在在 fbsd 下,所以會有 -liconv。

修正 LDFLAGS 後,使用上完全沒問題,不過檔案沒變小多少(全都有變小就是了)
看來不管那些 warning messages 是比較划算的,沒必要為了小一點點而大改 configure / Makefile
底下是修改 LDFLAGS 前後的 stripped binary 大小變化
gcin 169268 -> 169236
gcin-gb-toggle 7720 -> 7440
gcin-message 8272 -> 7992
gcin-setup 60392 -> 60232
gcin-setup-tab 55776 -> 55744
gcin2tab 14028 -> 13940
gtab-merge 11120 -> 10840
juyin-learn 18856 -> 18632
phoa2d 10168 -> 9936
phod2a 14312 -> 14184
sim2trad 10004 -> 9116
tsa2d32 13100 -> 12868
tsd2a 7676 -> 7396
tsd2a32 7676 -> 7396
tslearn 31140 -> 31076
im-gcin.so 10108 -> 10052
libqgcin.so 28892 -> 28596

我記得(印象中),沒用到的 link 也不會真的去 link,所以對可執行檔大小及執行速度的影響很小。
而且,ldd 是 recursively 列出 DSO,有些並不是直接用到的。
