Information
この情報は2013/10/28時点での解決方法です。
現在はmbed-src、標準ライブラリで問題なくコンパイルが可能です。
・使う物
LPC1114FN28
mbed SDK
LPC1114FN28でmbed-SDKのLibraryを使うとCompile出来ない。（2013/10/28）
パスが通ってないだけのようなのでファイルを以下に移動する。
| mbed-src\targets\cmsis\TARGET_NXP\TARGET_LPC11XX_11CXX\ mbed-src\targets\cmsis\TARGET_NXP\TARGET_LPC11XX_11CXX\TARGET_LPC11XX\ |
にあるファイルをすべて
| mbed-src\targets\cmsis\TARGET_NXP\ |
へ移動
mbed-src\targets\cmsis\TARGET_NXP\TARGET_LPC11XX_11CXX\にある
| TOOLCHAIN_ARM_MICRO |
をフォルダごと
| mbed-src\targets\cmsis\TARGET_NXP\ |
へ移動
| mbed-src\targets\hal\TARGET_NXP\TARGET_LPC11XX_11CXX\ mbed-src\targets\hal\TARGET_NXP\TARGET_LPC11XX_11CXX\TARGET_LPC11XX\ |
にあるファイルをすべて
| mbed-src\targets\hal\TARGET_NXP\ |
へ移動
移動後は以下のような構成になると思います。
※不要なファイルは削除してあります。

ファイルの移動が面倒なので以下に本家からフォークしたライブラリを置いておきます。

エラーが出力される場合
"TOOLCHAIN_ARM_MICRO"が無いとエラーになる。
| Error: Undefined symbol _initial_sp (referred from entry2.o). Error: Undefined symbol _heap_base (referred from malloc.o). Error: Undefined symbol _heap_limit (referred from malloc.o). |
LPC1114FN28はMicrolibを使ってCompileされるため上記のエラーになるようです。

-/* In the M0, there is no VTOR. In the LPC range such as the LPC11U,
- * whilst the vector table may only be something like 48 entries (192 bytes, 0xC0),
- * the SYSMEMREMAP register actually remaps the memory from 0x10000000-0x100001FF
- * to adress 0x0-0x1FF. In this case, RAM can be addressed at both 0x10000000 and 0x0
- *
- * If we just copy the vectors to RAM and switch the SYSMEMMAP, any accesses to FLASH
- * above the vector table before 0x200 will actually go to RAM. So we need to provide
- * a solution where the compiler gets the right results based on the memory map
- *
- * Option 1 - We allocate and copy 0x200 of RAM rather than just the table
- * - const data and instructions before 0x200 will be copied to and fetched/exec from RAM
- * - RAM overhead: 0x200 - 0xC0 = 320 bytes, FLASH overhead: 0
- *
- * Option 2 - We pad the flash to 0x200 to ensure the compiler doesn't allocate anything there
- * - No flash accesses will go to ram, as there will be nothing there
- * - RAM only needs to be allocated for the vectors, as all other ram addresses are normal
- * - RAM overhead: 0, FLASH overhead: 320 bytes
- *
- * Option 2 is the one to go for, as RAM is the most valuable resource
